dynamic differential scanning calorimetry. The imide-amines were prepared by reacting 1 mole of benzophenone 3,3′,4,4′-tetracarboxylic acid dianhydride (B) with 2.5 moles of 4,4′-diaminodiphenyl ether (E)/ or 4,4′-diaminodiphenyl methane (M)/ or 4,4′-diaminodiphenylsulfone (S) and designated as BE/ or BM/ or BS. The mixture of imide-amines and DDS at ratio of 0:1, 0.25:0.75, 0.5:0.5, 0.75:0.25 and 1:0 were used to investigate the curing behaviour of DGEBA. The multiple heating rate method (5, 10, 15 and 20°C min−1) was used to study the curing kinetics of epoxy resins. The peak exotherm temperature was found to be dependent on the heating rate, structure of imide-amines as well as on the ratio of imide-amine: DDS used. A broad exotherm was observed in the temperature range of 180–230°C on curing with mixture of imide-amines and DDS. Curing of DGEBA with mixture of imide-amines and/or DDS resulted in a decrease in characteristic curing temperatures. Activation energy of curing reaction as determined in accordance to the Ozawa’s method was found to be dependent on the structure of amine. The thermal stability of the isothermally cured resins was also evaluated using dynamic thermogravimetry in a nitrogen atmosphere.

Six imide–amines of varying structure were synthesized by reacting 1 mol of naphthalene 1,4,5,8-tetracarboxylic dianhydride (N) or 4,4′-oxodiphthalic anhydride (O) with excess (>2 mol) of 4,4′-diaminodiphenylether [E] or 4,4′-diaminodiphenyl methane [M] or 4,4′-diaminodiphenyl sulfone [S]. The imide–amines prepared by reacting O or N with S, M, and E have been designated as OS/NS; OM/NM, and OE/NE, respectively. Structural characterization of imide–amines was done using FTIR, 1H NMR, 13C NMR, and elemental analysis. The curing behavior of DGEBA in the presence of stoichiometric amount of imide–amines was investigated by recording DSC scans. A broad exothermic transition was observed and the peak exotherm temperature was found to be dependent on the structure of imide–amines. The peak exotherm temperature (Tp) was lowest in case of imide–amines OE and highest in case of imide–amines NS/OS.

The imide-amines were prepared by reacting 1 mole of naphthalene 1,4,5,8-tetracarboxylic dianhydride (N) and 4,4′-oxodiphthalic anhydride (O) with 2.5 moles of 4,4′-diaminodiphenyl ether (E) or 4,4′-diaminodiphenyl methane (M) or 4,4′-diaminodiphenylsulfone (S) and designated as NE/OE or NM/OM or NS/OS. The mixture of the imide-amines and DDS at ratio of 0:1, 0.25:0.75, 0.5:0.5, 0.75:0.25 and 1:0 were used to investigate the curing behaviour of DGEBA. A single exotherm was observed on curing with mixture of imide-amines and DDS. This clearly shows that the two amines act as co-curing agents. Curing temperatures were higher with imide-amines having sulfone linkage irrespective of anhydride. Curing of DGEBA with mixture of imide-amines and or DDS resulted in a decrease in characteristic curing temperatures. The thermal stability of the isothermally cured resins was also evaluated using dynamic thermogravimetry in a nitrogen atmosphere. The char yield was higher in case of resins cured imide-amines based on N and E.

the crystal structure of human DNA-TopoI and the recently reported Leishmania donavani DNA-TopoI. Additionally, the binding site interactions of amino derivatives of diospyrin with human TopoI were studied extensively. Based on the docking results, binding modes of diospyrin with the human and leishmanial TopoI catalytic core were predicted. The parallel use of two efficient and predictive docking programs, GOLD and Ligandfit, allowed mutual validation of the predicted binding poses. A reasonably good correlation coefficient between the calculated docking scores and the experimentally determined cytotoxicity helped in validating the docking method. Furthermore, a structure-based pharmacophore model was developed for L. donavani DNA-TopoI inhibition which helped in elucidating the topological and spatial requirements of the ligand-receptor interactions. This study provides an understanding of the structural basis of ligand binding to the topoisomerase receptor, which may be used for the structure-based design of potent and novel ligands for anticancer and antileishmanial therapy. To our knowledge, this is the first report of a binding mode exploration study for diospyrin and its derivatives as inhibitors of the leishmanial and human TopoI enzymes.","publication_date":{"day":null,"month":null,"year":2007,"errors":{}},"publication_name":"Bioorganic \u0026 Medicinal Chemistry Letters","grobid_abstract_attachment_id":48601891},"translated_abstract":null,"internal_url":"https://www.academia.edu/7095336/RETRACTED_A_computational_docking_study_for_prediction_of_binding_mode_of_diospyrin_and_derivatives_Inhibitors_of_human_and_leishmanial_DNA_topoisomerase_I","translated_internal_url":"","created_at":"2014-05-19T15:42:28.361-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":12189830,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":48601891,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/48601891/thumbnails/1.jpg","file_name":"j.bmcl.2007.05.08220160905-18527-1s5posf.pdf","download_url":"https://www.academia.edu/attachments/48601891/download_file?st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"RETRACTED_A_computational_docking_study.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/48601891/j.bmcl.2007.05.08220160905-18527-1s5posf-libre.pdf?1473131772=\u0026response-content-disposition=attachment%3B+filename%3DRETRACTED_A_computational_docking_study.pdf\u0026Expires=1732510780\u0026Signature=IRDFfS9PF54YKQftCoMVFQCg-vKevrmXNY44ULGu0W2EOMfMQu795k8-5GE8Fev6RSWxSMSwYwm41hTbsuMv7TJUIjbPfXi7rCRDgS6XFFNLxs-gzFXV9Atx9Gv~QMEkXOXnEOZNloQxbMHIrd77vAo4lfvI6sKE~Yyc3MM~RGW0YosqCS2xhcz6wcM~ZXnCII6B4MwSgghggKKVzgn32aNsqnqUkl1H~i9o49xZ0tapFzQHwBG90s7cHUqTx9ANjjy-u83YavQwfLJRTDZ-2pDIXW00P1yqRvAuR7n4cjBjEigjMS5mavdbI2~DxHTNikQriuyMUAaYC2ZSJHnkFg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"RETRACTED_A_computational_docking_study_for_prediction_of_binding_mode_of_diospyrin_and_derivatives_Inhibitors_of_human_and_leishmanial_DNA_topoisomerase_I","translated_slug":"","page_count":9,"language":"en","content_type":"Work","owner":{"id":12189830,"first_name":"Pooja","middle_initials":null,"last_name":"Sharma","page_name":"PoojaSharma71","domain_name":"independent","created_at":"2014-05-19T15:41:35.134-07:00","display_name":"Pooja Sharma","url":"https://independent.academia.edu/PoojaSharma71"},"attachments":[{"id":48601891,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/48601891/thumbnails/1.jpg","file_name":"j.bmcl.2007.05.08220160905-18527-1s5posf.pdf","download_url":"https://www.academia.edu/attachments/48601891/download_file?st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"RETRACTED_A_computational_docking_study.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/48601891/j.bmcl.2007.05.08220160905-18527-1s5posf-libre.pdf?1473131772=\u0026response-content-disposition=attachment%3B+filename%3DRETRACTED_A_computational_docking_study.pdf\u0026Expires=1732510780\u0026Signature=IRDFfS9PF54YKQftCoMVFQCg-vKevrmXNY44ULGu0W2EOMfMQu795k8-5GE8Fev6RSWxSMSwYwm41hTbsuMv7TJUIjbPfXi7rCRDgS6XFFNLxs-gzFXV9Atx9Gv~QMEkXOXnEOZNloQxbMHIrd77vAo4lfvI6sKE~Yyc3MM~RGW0YosqCS2xhcz6wcM~ZXnCII6B4MwSgghggKKVzgn32aNsqnqUkl1H~i9o49xZ0tapFzQHwBG90s7cHUqTx9ANjjy-u83YavQwfLJRTDZ-2pDIXW00P1yqRvAuR7n4cjBjEigjMS5mavdbI2~DxHTNikQriuyMUAaYC2ZSJHnkFg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":531,"name":"Organic Chemistry","url":"https://www.academia.edu/Documents/in/Organic_Chemistry"},{"id":53293,"name":"Software","url":"https://www.academia.edu/Documents/in/Software"},{"id":64568,"name":"Humans","url":"https://www.academia.edu/Documents/in/Humans"},{"id":69542,"name":"Computer Simulation","url":"https://www.academia.edu/Documents/in/Computer_Simulation"},{"id":99234,"name":"Animals","url":"https://www.academia.edu/Documents/in/Animals"},{"id":152961,"name":"Naphthoquinones","url":"https://www.academia.edu/Documents/in/Naphthoquinones"},{"id":296798,"name":"Hydrogen Bonding","url":"https://www.academia.edu/Documents/in/Hydrogen_Bonding"},{"id":649537,"name":"Molecular Conformation","url":"https://www.academia.edu/Documents/in/Molecular_Conformation"},{"id":728493,"name":"Bioorganic and medicinal Chemistry","url":"https://www.academia.edu/Documents/in/Bioorganic_and_medicinal_Chemistry"},{"id":1010725,"name":"Protein Binding","url":"https://www.academia.edu/Documents/in/Protein_Binding"},{"id":1222191,"name":"Ligands","url":"https://www.academia.edu/Documents/in/Ligands"}],"urls":[{"id":2924023,"url":"http://www.sciencedirect.com/science/article/pii/S0960894X0700649X"}]}, dispatcherData: dispatcherData });

The samples have been characterized for nanophase, structural and luminescent properties.","publication_date":{"day":null,"month":null,"year":2004,"errors":{}},"publication_name":"Journal of Crystal Growth","grobid_abstract_attachment_id":48601947},"translated_abstract":null,"internal_url":"https://www.academia.edu/7095334/Synthesis_of_nanocrystals_of_long_persisting_phosphor_by_modified_combustion_technique","translated_internal_url":"","created_at":"2014-05-19T15:42:20.876-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":12189830,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":48601947,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/48601947/thumbnails/1.jpg","file_name":"Synthesis_of_Nanocrystals_of_Long_Persis20160905-10695-132stk0.pdf","download_url":"https://www.academia.edu/attachments/48601947/download_file?st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Synthesis_of_nanocrystals_of_long_persis.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/48601947/Synthesis_of_Nanocrystals_of_Long_Persis20160905-10695-132stk0-libre.pdf?1473131771=\u0026response-content-disposition=attachment%3B+filename%3DSynthesis_of_nanocrystals_of_long_persis.pdf\u0026Expires=1732510780\u0026Signature=gHK7-U7IX28zy8klURcOqCBecKcJZtpCWXmlQySlzdiTFeixalo41G1uyWLsHCUfs-wnUza4UxEkDaz~7DTfZM46kbNYDurCiJvx2RGYZtq3lgOizhJMZA1bZcCCrVj3qkT6qhkBXU6c~W7C3aSrQPfuIE-aP3wtYe-crTxNtMViTyY4wdcr--iF39zXC~ZeatCnyX8buFGc95jBsbzpajzlXdJBtOx6D8xAANcRKeyC3lp9myO991iXuh3z0HobqIG7bWaCLkcdPEadzi8eWBzPlLygoI3lC4RB7qACJe~tjG2qqX~oRMOVxvzgD8ScNGYQUgWL~kn-epyMvlOtdw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Synthesis_of_nanocrystals_of_long_persisting_phosphor_by_modified_combustion_technique","translated_slug":"","page_count":15,"language":"en","content_type":"Work","owner":{"id":12189830,"first_name":"Pooja","middle_initials":null,"last_name":"Sharma","page_name":"PoojaSharma71","domain_name":"independent","created_at":"2014-05-19T15:41:35.134-07:00","display_name":"Pooja Sharma","url":"https://independent.academia.edu/PoojaSharma71"},"attachments":[{"id":48601947,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/48601947/thumbnails/1.jpg","file_name":"Synthesis_of_Nanocrystals_of_Long_Persis20160905-10695-132stk0.pdf","download_url":"https://www.academia.edu/attachments/48601947/download_file?st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Synthesis_of_nanocrystals_of_long_persis.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/48601947/Synthesis_of_Nanocrystals_of_Long_Persis20160905-10695-132stk0-libre.pdf?1473131771=\u0026response-content-disposition=attachment%3B+filename%3DSynthesis_of_nanocrystals_of_long_persis.pdf\u0026Expires=1732510780\u0026Signature=gHK7-U7IX28zy8klURcOqCBecKcJZtpCWXmlQySlzdiTFeixalo41G1uyWLsHCUfs-wnUza4UxEkDaz~7DTfZM46kbNYDurCiJvx2RGYZtq3lgOizhJMZA1bZcCCrVj3qkT6qhkBXU6c~W7C3aSrQPfuIE-aP3wtYe-crTxNtMViTyY4wdcr--iF39zXC~ZeatCnyX8buFGc95jBsbzpajzlXdJBtOx6D8xAANcRKeyC3lp9myO991iXuh3z0HobqIG7bWaCLkcdPEadzi8eWBzPlLygoI3lC4RB7qACJe~tjG2qqX~oRMOVxvzgD8ScNGYQUgWL~kn-epyMvlOtdw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":4120,"name":"Crystal Growth","url":"https://www.academia.edu/Documents/in/Crystal_Growth"},{"id":758278,"name":"Large Scale","url":"https://www.academia.edu/Documents/in/Large_Scale"}],"urls":[{"id":2924022,"url":"http://www.sciencedirect.com/science/article/pii/S002202480400870X"}]}, dispatcherData: dispatcherData });

The evolution of hazardous NxOx gases during the customary combustion reaction was completely eliminated by employing an innovative complex formation route. Another fascinating feature of the process was that, a slight change in the processing conditions ensured the synthesis of either nanoparticles or nanowires. The photoluminescence spectrum of nanophosphor showed a slight blue shift in emission ($511 nm) as compared to the bulk phosphor ($520 nm). The afterglow (decay) profiles of SAC nanoparticles, nanowires and bulk phosphor were compared.

It has been observed that a slight modification in the processing parameters such as type of reducing atmosphere, stoichiometric excess of one or more constituents, nature of fluxes, and intentional addition of carbon or rare-earth halides can drastically shift the emission colours of the SRA phosphor in the visible spectrum. X-ray diffraction analysis and scanning electron microscopy observations of the samples revealed the formation of different crystalline phases related to the SRA system. The luminescence measurements showed that the decay times varied with the emission colours of the samples.","publication_date":{"day":null,"month":null,"year":2003,"errors":{}},"publication_name":"Journal of Physics D-applied Physics","grobid_abstract_attachment_id":48601963},"translated_abstract":null,"internal_url":"https://www.academia.edu/7095332/Tuning_of_emission_colours_in_strontium_aluminate_long_persisting_phosphor","translated_internal_url":"","created_at":"2014-05-19T15:42:20.310-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":12189830,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":48601963,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/48601963/thumbnails/1.jpg","file_name":"Tuning_of_emission_colours_in_strontium_20160905-24091-1n93sxp.pdf","download_url":"https://www.academia.edu/attachments/48601963/download_file?st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Tuning_of_emission_colours_in_strontium.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/48601963/Tuning_of_emission_colours_in_strontium_20160905-24091-1n93sxp-libre.pdf?1473131770=\u0026response-content-disposition=attachment%3B+filename%3DTuning_of_emission_colours_in_strontium.pdf\u0026Expires=1732510780\u0026Signature=Y9QOs6RHeG337pWE~cnDCb2IflPMIomXxEADHNt33jSvQjV34XwckPrl9CdpzDNHqQZP2mWygGO7NQkVDXFbcRU~Zo-7CsxF-zOVsxwtAFE2~-0csk~avMCYRvKKnYMXqS1TRkzieyqsQ0nqyxaX7tA370qnJBeKoaOuPQO0V2LmcZpXfAKWF4MXuPoOMbakuF7yLdwwUwP8HAoZVlR-ekokkaB8c2oQki-8FYgG-URiPNAdfbRWkTQWF4OeOevYzRGhDw2mRW2QUsHqLHnBxFmpw0CaX13cuIg-ZuiDY-jM8-tPlbrMm3cPBvUoRWiN0eo1U6teK3QU8PGs4GQLsg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Tuning_of_emission_colours_in_strontium_aluminate_long_persisting_phosphor","translated_slug":"","page_count":5,"language":"en","content_type":"Work","owner":{"id":12189830,"first_name":"Pooja","middle_initials":null,"last_name":"Sharma","page_name":"PoojaSharma71","domain_name":"independent","created_at":"2014-05-19T15:41:35.134-07:00","display_name":"Pooja Sharma","url":"https://independent.academia.edu/PoojaSharma71"},"attachments":[{"id":48601963,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/48601963/thumbnails/1.jpg","file_name":"Tuning_of_emission_colours_in_strontium_20160905-24091-1n93sxp.pdf","download_url":"https://www.academia.edu/attachments/48601963/download_file?st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Tuning_of_emission_colours_in_strontium.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/48601963/Tuning_of_emission_colours_in_strontium_20160905-24091-1n93sxp-libre.pdf?1473131770=\u0026response-content-disposition=attachment%3B+filename%3DTuning_of_emission_colours_in_strontium.pdf\u0026Expires=1732510780\u0026Signature=Y9QOs6RHeG337pWE~cnDCb2IflPMIomXxEADHNt33jSvQjV34XwckPrl9CdpzDNHqQZP2mWygGO7NQkVDXFbcRU~Zo-7CsxF-zOVsxwtAFE2~-0csk~avMCYRvKKnYMXqS1TRkzieyqsQ0nqyxaX7tA370qnJBeKoaOuPQO0V2LmcZpXfAKWF4MXuPoOMbakuF7yLdwwUwP8HAoZVlR-ekokkaB8c2oQki-8FYgG-URiPNAdfbRWkTQWF4OeOevYzRGhDw2mRW2QUsHqLHnBxFmpw0CaX13cuIg-ZuiDY-jM8-tPlbrMm3cPBvUoRWiN0eo1U6teK3QU8PGs4GQLsg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":48,"name":"Engineering","url":"https://www.academia.edu/Documents/in/Engineering"},{"id":10655,"name":"Scanning Electron Microscopy","url":"https://www.academia.edu/Documents/in/Scanning_Electron_Microscopy"},{"id":33912,"name":"Doping","url":"https://www.academia.edu/Documents/in/Doping"},{"id":35267,"name":"Photoluminescence","url":"https://www.academia.edu/Documents/in/Photoluminescence"},{"id":76714,"name":"Color","url":"https://www.academia.edu/Documents/in/Color"},{"id":118582,"name":"Physical sciences","url":"https://www.academia.edu/Documents/in/Physical_sciences"},{"id":186080,"name":"XRD","url":"https://www.academia.edu/Documents/in/XRD"},{"id":321836,"name":"Spectrum","url":"https://www.academia.edu/Documents/in/Spectrum"},{"id":395801,"name":"Rare Earth","url":"https://www.academia.edu/Documents/in/Rare_Earth"},{"id":566559,"name":"Stoichiometry","url":"https://www.academia.edu/Documents/in/Stoichiometry"},{"id":580255,"name":"Phosphors","url":"https://www.academia.edu/Documents/in/Phosphors"},{"id":902446,"name":"X Ray Diffraction Analysis","url":"https://www.academia.edu/Documents/in/X_Ray_Diffraction_Analysis"},{"id":973996,"name":"Process Parameters","url":"https://www.academia.edu/Documents/in/Process_Parameters"}],"urls":[{"id":2924020,"url":"http://dx.doi.org/10.1088/0022-3727/36/18/012"}]}, dispatcherData: dispatcherData });

The appropriate usage of H 3 BO 3 in defining the crystal structure, morphology and momentous variation in luminescent properties of calcium aluminate long persisting (LP) phosphor is systematically studied and presented. The results attribute two major roles for H 3 BO 3 ; as a flux for promoting the formation of required crystalline phase, when added in the amounts less than 10 mol% and as one of the precursors for the formation of aluminoborate complex when added above 10 mol%. This amount could be treated as a threshold for aluminoborate complex formation. Luminescent studies revealed that out of all phases identified, CaAl 2 O 4 is the only phase contributing for maximum photoluminescence (PL) augmentation and long persistence (10-12 h) from Eu 2+ and Nd 3+ ions, respectively. The relevant chemistry and reaction mechanism involved during solid-state synthesis of rare-earth doped calcium aluminate LP phosphor system have been discussed with greater emphasis on the luminescent properties affected with the addition of boric acid.","publication_date":{"day":null,"month":null,"year":2007,"errors":{}},"publication_name":"Materials Chemistry and Physics","grobid_abstract_attachment_id":48601946},"translated_abstract":null,"internal_url":"https://www.academia.edu/7095331/Role_of_boric_acid_in_synthesis_and_tailoring_the_properties_of_calcium_aluminate_phosphor","translated_internal_url":"","created_at":"2014-05-19T15:42:19.917-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":12189830,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":48601946,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/48601946/thumbnails/1.jpg","file_name":"Role_of_boric_acid_in_synthesis_and_tail20160905-1487-1ijf58c.pdf","download_url":"https://www.academia.edu/attachments/48601946/download_file?st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Role_of_boric_acid_in_synthesis_and_tail.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/48601946/Role_of_boric_acid_in_synthesis_and_tail20160905-1487-1ijf58c-libre.pdf?1473131771=\u0026response-content-disposition=attachment%3B+filename%3DRole_of_boric_acid_in_synthesis_and_tail.pdf\u0026Expires=1732510780\u0026Signature=b6vzcxd-ztVMu~FHuz3vfNHAotxcBU6Ym~KOgwj-2eCKudaH8d5xDpkRiBnH-V9ekfHHN14VENbGmkUxjX6VzxmYldZelUA-hEmP70S4iJW7gx6qbhjMicj5jQRHsY3lTbYHFmPBJCcUzWzz3swLMsBHpRwi84s8-PENwLKyLlt3JgPaG7KSUdMnJDpP20g~s-SrtYkyXc7TBzyhM72AwoVHyssQhBQMrmU7z5zjrPRCwaF29r8i1MxwXXYVXDDsVu6s4ALPv7xuy842g~sqFR9gzqftuiw~C-GSj38AsjSiKQs8EZgr4ihRB0rLPUAYSj9GQuHzvQLL4h3p~Gz8Rg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Role_of_boric_acid_in_synthesis_and_tailoring_the_properties_of_calcium_aluminate_phosphor","translated_slug":"","page_count":8,"language":"en","content_type":"Work","owner":{"id":12189830,"first_name":"Pooja","middle_initials":null,"last_name":"Sharma","page_name":"PoojaSharma71","domain_name":"independent","created_at":"2014-05-19T15:41:35.134-07:00","display_name":"Pooja Sharma","url":"https://independent.academia.edu/PoojaSharma71"},"attachments":[{"id":48601946,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/48601946/thumbnails/1.jpg","file_name":"Role_of_boric_acid_in_synthesis_and_tail20160905-1487-1ijf58c.pdf","download_url":"https://www.academia.edu/attachments/48601946/download_file?st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Role_of_boric_acid_in_synthesis_and_tail.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/48601946/Role_of_boric_acid_in_synthesis_and_tail20160905-1487-1ijf58c-libre.pdf?1473131771=\u0026response-content-disposition=attachment%3B+filename%3DRole_of_boric_acid_in_synthesis_and_tail.pdf\u0026Expires=1732510780\u0026Signature=b6vzcxd-ztVMu~FHuz3vfNHAotxcBU6Ym~KOgwj-2eCKudaH8d5xDpkRiBnH-V9ekfHHN14VENbGmkUxjX6VzxmYldZelUA-hEmP70S4iJW7gx6qbhjMicj5jQRHsY3lTbYHFmPBJCcUzWzz3swLMsBHpRwi84s8-PENwLKyLlt3JgPaG7KSUdMnJDpP20g~s-SrtYkyXc7TBzyhM72AwoVHyssQhBQMrmU7z5zjrPRCwaF29r8i1MxwXXYVXDDsVu6s4ALPv7xuy842g~sqFR9gzqftuiw~C-GSj38AsjSiKQs8EZgr4ihRB0rLPUAYSj9GQuHzvQLL4h3p~Gz8Rg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":56,"name":"Materials Engineering","url":"https://www.academia.edu/Documents/in/Materials_Engineering"},{"id":300,"name":"Mathematics","url":"https://www.academia.edu/Documents/in/Mathematics"},{"id":2305,"name":"Materials Chemistry","url":"https://www.academia.edu/Documents/in/Materials_Chemistry"},{"id":50630,"name":"Crystal structure","url":"https://www.academia.edu/Documents/in/Crystal_structure"},{"id":394500,"name":"Boric Acid","url":"https://www.academia.edu/Documents/in/Boric_Acid"},{"id":395801,"name":"Rare Earth","url":"https://www.academia.edu/Documents/in/Rare_Earth"},{"id":845691,"name":"Reaction Mechanism","url":"https://www.academia.edu/Documents/in/Reaction_Mechanism"}],"urls":[{"id":2924019,"url":"http://www.sciencedirect.com/science/article/pii/S0254058406001118"}]}, dispatcherData: dispatcherData });

The sample ®red in N 2 atmosphere with aluminum and bromine shows predominantly green emission with a peak around 530 nm whereas the sample prepared under H 2 S and HBr shows the broadest emission spectrum with multiple peaks. These peaks may arise out of different possible bands of copper, self-activated luminescence of ZnS and association of copper with some of the donor levels formed because of the higher reactivity of HBr. All the samples have been found to obey the relation B B 0 exp.(Àb/V 0.5 ) which has been discussed using bipolar tunnel emission model. The frequency variation of brightness is linear. Samples containing bromine show multiple secondary peaks indicating that bromine helps in formation of multiple shallow traps. #","publication_date":{"day":null,"month":null,"year":2003,"errors":{}},"publication_name":"Materials Research Bulletin","grobid_abstract_attachment_id":48601907},"translated_abstract":null,"internal_url":"https://www.academia.edu/7095330/Characterization_of_ZnS_Cu_Br_electroluminescent_phosphor_prepared_by_new_route","translated_internal_url":"","created_at":"2014-05-19T15:42:19.576-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":12189830,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":48601907,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/48601907/thumbnails/1.jpg","file_name":"Characterization_of_ZnSCu_Br_electrolumi20160905-24097-dy9u88.pdf","download_url":"https://www.academia.edu/attachments/48601907/download_file?st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Characterization_of_ZnS_Cu_Br_electrolum.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/48601907/Characterization_of_ZnSCu_Br_electrolumi20160905-24097-dy9u88-libre.pdf?1473131771=\u0026response-content-disposition=attachment%3B+filename%3DCharacterization_of_ZnS_Cu_Br_electrolum.pdf\u0026Expires=1732510780\u0026Signature=biDQqN~MHb0d-P-yehUVASn1Fcni0sk1mcY83nK7IK9YZlSvUWyL2Eq0blGzXtDIPhHrzQtrVLCPGNcV1M0FrN4cKVZu9iTuWKAHDPFVNXtEpuOGIsWu5zVCxlxVflA0E2RvilpEtAtEHWZqwQrUWe9fVXpUfYD2m8gozQqmHtr7opfHe3alO5AaG2PFheTWed82AtvbFsT1r2o4SeK~ep8ABLkEfcMMAL3H2k0y1iccbW-9TOJ~L3M5RCFUFimw8i6gWrWYqB1U3iaut~IjsJ9dmqG9HgptPFLDmKrp1eTDoyW6szfPrm-OnRkw50SqfkFA4Pm~sQcNtxFWwATb-g__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Characterization_of_ZnS_Cu_Br_electroluminescent_phosphor_prepared_by_new_route","translated_slug":"","page_count":10,"language":"en","content_type":"Work","owner":{"id":12189830,"first_name":"Pooja","middle_initials":null,"last_name":"Sharma","page_name":"PoojaSharma71","domain_name":"independent","created_at":"2014-05-19T15:41:35.134-07:00","display_name":"Pooja Sharma","url":"https://independent.academia.edu/PoojaSharma71"},"attachments":[{"id":48601907,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/48601907/thumbnails/1.jpg","file_name":"Characterization_of_ZnSCu_Br_electrolumi20160905-24097-dy9u88.pdf","download_url":"https://www.academia.edu/attachments/48601907/download_file?st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Characterization_of_ZnS_Cu_Br_electrolum.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/48601907/Characterization_of_ZnSCu_Br_electrolumi20160905-24097-dy9u88-libre.pdf?1473131771=\u0026response-content-disposition=attachment%3B+filename%3DCharacterization_of_ZnS_Cu_Br_electrolum.pdf\u0026Expires=1732510780\u0026Signature=biDQqN~MHb0d-P-yehUVASn1Fcni0sk1mcY83nK7IK9YZlSvUWyL2Eq0blGzXtDIPhHrzQtrVLCPGNcV1M0FrN4cKVZu9iTuWKAHDPFVNXtEpuOGIsWu5zVCxlxVflA0E2RvilpEtAtEHWZqwQrUWe9fVXpUfYD2m8gozQqmHtr7opfHe3alO5AaG2PFheTWed82AtvbFsT1r2o4SeK~ep8ABLkEfcMMAL3H2k0y1iccbW-9TOJ~L3M5RCFUFimw8i6gWrWYqB1U3iaut~IjsJ9dmqG9HgptPFLDmKrp1eTDoyW6szfPrm-OnRkw50SqfkFA4Pm~sQcNtxFWwATb-g__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":56,"name":"Materials Engineering","url":"https://www.academia.edu/Documents/in/Materials_Engineering"},{"id":10650,"name":"Materials","url":"https://www.academia.edu/Documents/in/Materials"},{"id":14925,"name":"Heat Treatment","url":"https://www.academia.edu/Documents/in/Heat_Treatment"},{"id":32910,"name":"Sample Preparation","url":"https://www.academia.edu/Documents/in/Sample_Preparation"},{"id":33912,"name":"Doping","url":"https://www.academia.edu/Documents/in/Doping"},{"id":80692,"name":"Copper","url":"https://www.academia.edu/Documents/in/Copper"},{"id":158914,"name":"Luminescence","url":"https://www.academia.edu/Documents/in/Luminescence"},{"id":321836,"name":"Spectrum","url":"https://www.academia.edu/Documents/in/Spectrum"},{"id":991011,"name":"Electroluminescence","url":"https://www.academia.edu/Documents/in/Electroluminescence"},{"id":1152821,"name":"Chemical Synthesis","url":"https://www.academia.edu/Documents/in/Chemical_Synthesis"},{"id":2217031,"name":"Spectral Energy Distribution","url":"https://www.academia.edu/Documents/in/Spectral_Energy_Distribution"}],"urls":[{"id":2924018,"url":"http://www.sciencedirect.com/science/article/pii/S0025540802010279"}]}, dispatcherData: dispatcherData });

The dependence of initial brightness and observed afterglow characteristics on various thermal processing parameters such as heating rates, time of constant heating and cooling rates have been investigated. It has been found that heating rates (\u003e625 • C h −1 ), time of constant heating (\u003c2 h at around 1200 • C) and cooling rates (\u003e250 • C h −1 ) resulted in non-uniform luminescent samples which are not excited under roomlight but under UV (365 nm). Whereas heating rates (\u003c300 • C h −1 ), time of constant heating (\u003e4 h at 1200 • C) and cooling rates (\u003c100 • C h −1 ) resulted in high-density ceramic compact (∼3100 kg m −3 ) samples with very low initial brightness but quite long afterglow under roomlight and UV excitation. An optimum of both fast rise and long afterglow under roomlight excitation has been achieved for the SRA samples fired with the heating rates of 300-625 • C h −1 , time of constant heating 2-4 h at around 1200 • C and cooling rates of 100-250 • C h −1 .

Six imide–amines of varying structure were synthesized by reacting 1 mol of naphthalene 1,4,5,8-tetracarboxylic dianhydride (N) or 4,4′-oxodiphthalic anhydride (O) with excess (>2 mol) of 4,4′-diaminodiphenylether [E] or 4,4′-diaminodiphenyl methane [M] or 4,4′-diaminodiphenyl sulfone [S]. The imide–amines prepared by reacting O or N with S, M, and E have been designated as OS/NS; OM/NM, and OE/NE, respectively. Structural characterization of imide–amines was done using FTIR, 1H NMR, 13C NMR, and elemental analysis. The curing behavior of DGEBA in the presence of stoichiometric amount of imide–amines was investigated by recording DSC scans. A broad exothermic transition was observed and the peak exotherm temperature was found to be dependent on the structure of imide–amines. The peak exotherm temperature (Tp) was lowest in case of imide–amines OE and highest in case of imide–amines NS/OS.

The imide-amines were prepared by reacting 1 mole of naphthalene 1,4,5,8-tetracarboxylic dianhydride (N) and 4,4′-oxodiphthalic anhydride (O) with 2.5 moles of 4,4′-diaminodiphenyl ether (E) or 4,4′-diaminodiphenyl methane (M) or 4,4′-diaminodiphenylsulfone (S) and designated as NE/OE or NM/OM or NS/OS. The mixture of the imide-amines and DDS at ratio of 0:1, 0.25:0.75, 0.5:0.5, 0.75:0.25 and 1:0 were used to investigate the curing behaviour of DGEBA. A single exotherm was observed on curing with mixture of imide-amines and DDS. This clearly shows that the two amines act as co-curing agents. Curing temperatures were higher with imide-amines having sulfone linkage irrespective of anhydride. Curing of DGEBA with mixture of imide-amines and or DDS resulted in a decrease in characteristic curing temperatures. The thermal stability of the isothermally cured resins was also evaluated using dynamic thermogravimetry in a nitrogen atmosphere.

the crystal structure of human DNA-TopoI and the recently reported Leishmania donavani DNA-TopoI. Additionally, the binding site interactions of amino derivatives of diospyrin with human TopoI were studied extensively. Based on the docking results, binding modes of diospyrin with the human and leishmanial TopoI catalytic core were predicted. The parallel use of two efficient and predictive docking programs, GOLD and Ligandfit, allowed mutual validation of the predicted binding poses. A reasonably good correlation coefficient between the calculated docking scores and the experimentally determined cytotoxicity helped in validating the docking method. Furthermore, a structure-based pharmacophore model was developed for L. donavani DNA-TopoI inhibition which helped in elucidating the topological and spatial requirements of the ligand-receptor interactions. This study provides an understanding of the structural basis of ligand binding to the topoisomerase receptor, which may be used for the structure-based design of potent and novel ligands for anticancer and antileishmanial therapy. To our knowledge, this is the first report of a binding mode exploration study for diospyrin and its derivatives as inhibitors of the leishmanial and human TopoI enzymes.","publication_date":{"day":null,"month":null,"year":2007,"errors":{}},"publication_name":"Bioorganic \u0026 Medicinal Chemistry Letters","grobid_abstract_attachment_id":48601891},"translated_abstract":null,"internal_url":"https://www.academia.edu/7095336/RETRACTED_A_computational_docking_study_for_prediction_of_binding_mode_of_diospyrin_and_derivatives_Inhibitors_of_human_and_leishmanial_DNA_topoisomerase_I","translated_internal_url":"","created_at":"2014-05-19T15:42:28.361-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":12189830,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":48601891,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/48601891/thumbnails/1.jpg","file_name":"j.bmcl.2007.05.08220160905-18527-1s5posf.pdf","download_url":"https://www.academia.edu/attachments/48601891/download_file?st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"RETRACTED_A_computational_docking_study.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/48601891/j.bmcl.2007.05.08220160905-18527-1s5posf-libre.pdf?1473131772=\u0026response-content-disposition=attachment%3B+filename%3DRETRACTED_A_computational_docking_study.pdf\u0026Expires=1732510780\u0026Signature=IRDFfS9PF54YKQftCoMVFQCg-vKevrmXNY44ULGu0W2EOMfMQu795k8-5GE8Fev6RSWxSMSwYwm41hTbsuMv7TJUIjbPfXi7rCRDgS6XFFNLxs-gzFXV9Atx9Gv~QMEkXOXnEOZNloQxbMHIrd77vAo4lfvI6sKE~Yyc3MM~RGW0YosqCS2xhcz6wcM~ZXnCII6B4MwSgghggKKVzgn32aNsqnqUkl1H~i9o49xZ0tapFzQHwBG90s7cHUqTx9ANjjy-u83YavQwfLJRTDZ-2pDIXW00P1yqRvAuR7n4cjBjEigjMS5mavdbI2~DxHTNikQriuyMUAaYC2ZSJHnkFg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"RETRACTED_A_computational_docking_study_for_prediction_of_binding_mode_of_diospyrin_and_derivatives_Inhibitors_of_human_and_leishmanial_DNA_topoisomerase_I","translated_slug":"","page_count":9,"language":"en","content_type":"Work","owner":{"id":12189830,"first_name":"Pooja","middle_initials":null,"last_name":"Sharma","page_name":"PoojaSharma71","domain_name":"independent","created_at":"2014-05-19T15:41:35.134-07:00","display_name":"Pooja Sharma","url":"https://independent.academia.edu/PoojaSharma71"},"attachments":[{"id":48601891,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/48601891/thumbnails/1.jpg","file_name":"j.bmcl.2007.05.08220160905-18527-1s5posf.pdf","download_url":"https://www.academia.edu/attachments/48601891/download_file?st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"RETRACTED_A_computational_docking_study.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/48601891/j.bmcl.2007.05.08220160905-18527-1s5posf-libre.pdf?1473131772=\u0026response-content-disposition=attachment%3B+filename%3DRETRACTED_A_computational_docking_study.pdf\u0026Expires=1732510780\u0026Signature=IRDFfS9PF54YKQftCoMVFQCg-vKevrmXNY44ULGu0W2EOMfMQu795k8-5GE8Fev6RSWxSMSwYwm41hTbsuMv7TJUIjbPfXi7rCRDgS6XFFNLxs-gzFXV9Atx9Gv~QMEkXOXnEOZNloQxbMHIrd77vAo4lfvI6sKE~Yyc3MM~RGW0YosqCS2xhcz6wcM~ZXnCII6B4MwSgghggKKVzgn32aNsqnqUkl1H~i9o49xZ0tapFzQHwBG90s7cHUqTx9ANjjy-u83YavQwfLJRTDZ-2pDIXW00P1yqRvAuR7n4cjBjEigjMS5mavdbI2~DxHTNikQriuyMUAaYC2ZSJHnkFg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":531,"name":"Organic Chemistry","url":"https://www.academia.edu/Documents/in/Organic_Chemistry"},{"id":53293,"name":"Software","url":"https://www.academia.edu/Documents/in/Software"},{"id":64568,"name":"Humans","url":"https://www.academia.edu/Documents/in/Humans"},{"id":69542,"name":"Computer Simulation","url":"https://www.academia.edu/Documents/in/Computer_Simulation"},{"id":99234,"name":"Animals","url":"https://www.academia.edu/Documents/in/Animals"},{"id":152961,"name":"Naphthoquinones","url":"https://www.academia.edu/Documents/in/Naphthoquinones"},{"id":296798,"name":"Hydrogen Bonding","url":"https://www.academia.edu/Documents/in/Hydrogen_Bonding"},{"id":649537,"name":"Molecular Conformation","url":"https://www.academia.edu/Documents/in/Molecular_Conformation"},{"id":728493,"name":"Bioorganic and medicinal Chemistry","url":"https://www.academia.edu/Documents/in/Bioorganic_and_medicinal_Chemistry"},{"id":1010725,"name":"Protein Binding","url":"https://www.academia.edu/Documents/in/Protein_Binding"},{"id":1222191,"name":"Ligands","url":"https://www.academia.edu/Documents/in/Ligands"}],"urls":[{"id":2924023,"url":"http://www.sciencedirect.com/science/article/pii/S0960894X0700649X"}]}, dispatcherData: dispatcherData });

It resulted in lowdensity voluminous mass in contrast to a solid lump by conventional solidstate method. The present work reports the changes made in the combustion process to achieve the homogenous incorporation of dopants and large-scale production of the nanophosphor in a short interval of time. The samples have been characterized for nanophase, structural and luminescent properties.","publication_date":{"day":null,"month":null,"year":2004,"errors":{}},"publication_name":"Journal of Crystal Growth","grobid_abstract_attachment_id":48601947},"translated_abstract":null,"internal_url":"https://www.academia.edu/7095334/Synthesis_of_nanocrystals_of_long_persisting_phosphor_by_modified_combustion_technique","translated_internal_url":"","created_at":"2014-05-19T15:42:20.876-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":12189830,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":48601947,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/48601947/thumbnails/1.jpg","file_name":"Synthesis_of_Nanocrystals_of_Long_Persis20160905-10695-132stk0.pdf","download_url":"https://www.academia.edu/attachments/48601947/download_file?st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Synthesis_of_nanocrystals_of_long_persis.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/48601947/Synthesis_of_Nanocrystals_of_Long_Persis20160905-10695-132stk0-libre.pdf?1473131771=\u0026response-content-disposition=attachment%3B+filename%3DSynthesis_of_nanocrystals_of_long_persis.pdf\u0026Expires=1732510780\u0026Signature=gHK7-U7IX28zy8klURcOqCBecKcJZtpCWXmlQySlzdiTFeixalo41G1uyWLsHCUfs-wnUza4UxEkDaz~7DTfZM46kbNYDurCiJvx2RGYZtq3lgOizhJMZA1bZcCCrVj3qkT6qhkBXU6c~W7C3aSrQPfuIE-aP3wtYe-crTxNtMViTyY4wdcr--iF39zXC~ZeatCnyX8buFGc95jBsbzpajzlXdJBtOx6D8xAANcRKeyC3lp9myO991iXuh3z0HobqIG7bWaCLkcdPEadzi8eWBzPlLygoI3lC4RB7qACJe~tjG2qqX~oRMOVxvzgD8ScNGYQUgWL~kn-epyMvlOtdw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Synthesis_of_nanocrystals_of_long_persisting_phosphor_by_modified_combustion_technique","translated_slug":"","page_count":15,"language":"en","content_type":"Work","owner":{"id":12189830,"first_name":"Pooja","middle_initials":null,"last_name":"Sharma","page_name":"PoojaSharma71","domain_name":"independent","created_at":"2014-05-19T15:41:35.134-07:00","display_name":"Pooja Sharma","url":"https://independent.academia.edu/PoojaSharma71"},"attachments":[{"id":48601947,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/48601947/thumbnails/1.jpg","file_name":"Synthesis_of_Nanocrystals_of_Long_Persis20160905-10695-132stk0.pdf","download_url":"https://www.academia.edu/attachments/48601947/download_file?st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Synthesis_of_nanocrystals_of_long_persis.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/48601947/Synthesis_of_Nanocrystals_of_Long_Persis20160905-10695-132stk0-libre.pdf?1473131771=\u0026response-content-disposition=attachment%3B+filename%3DSynthesis_of_nanocrystals_of_long_persis.pdf\u0026Expires=1732510780\u0026Signature=gHK7-U7IX28zy8klURcOqCBecKcJZtpCWXmlQySlzdiTFeixalo41G1uyWLsHCUfs-wnUza4UxEkDaz~7DTfZM46kbNYDurCiJvx2RGYZtq3lgOizhJMZA1bZcCCrVj3qkT6qhkBXU6c~W7C3aSrQPfuIE-aP3wtYe-crTxNtMViTyY4wdcr--iF39zXC~ZeatCnyX8buFGc95jBsbzpajzlXdJBtOx6D8xAANcRKeyC3lp9myO991iXuh3z0HobqIG7bWaCLkcdPEadzi8eWBzPlLygoI3lC4RB7qACJe~tjG2qqX~oRMOVxvzgD8ScNGYQUgWL~kn-epyMvlOtdw__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":4120,"name":"Crystal Growth","url":"https://www.academia.edu/Documents/in/Crystal_Growth"},{"id":758278,"name":"Large Scale","url":"https://www.academia.edu/Documents/in/Large_Scale"}],"urls":[{"id":2924022,"url":"http://www.sciencedirect.com/science/article/pii/S002202480400870X"}]}, dispatcherData: dispatcherData });

The evolution of hazardous NxOx gases during the customary combustion reaction was completely eliminated by employing an innovative complex formation route. Another fascinating feature of the process was that, a slight change in the processing conditions ensured the synthesis of either nanoparticles or nanowires. The photoluminescence spectrum of nanophosphor showed a slight blue shift in emission ($511 nm) as compared to the bulk phosphor ($520 nm). The afterglow (decay) profiles of SAC nanoparticles, nanowires and bulk phosphor were compared.

It has been observed that a slight modification in the processing parameters such as type of reducing atmosphere, stoichiometric excess of one or more constituents, nature of fluxes, and intentional addition of carbon or rare-earth halides can drastically shift the emission colours of the SRA phosphor in the visible spectrum. X-ray diffraction analysis and scanning electron microscopy observations of the samples revealed the formation of different crystalline phases related to the SRA system. The luminescence measurements showed that the decay times varied with the emission colours of the samples.","publication_date":{"day":null,"month":null,"year":2003,"errors":{}},"publication_name":"Journal of Physics D-applied Physics","grobid_abstract_attachment_id":48601963},"translated_abstract":null,"internal_url":"https://www.academia.edu/7095332/Tuning_of_emission_colours_in_strontium_aluminate_long_persisting_phosphor","translated_internal_url":"","created_at":"2014-05-19T15:42:20.310-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":12189830,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":48601963,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/48601963/thumbnails/1.jpg","file_name":"Tuning_of_emission_colours_in_strontium_20160905-24091-1n93sxp.pdf","download_url":"https://www.academia.edu/attachments/48601963/download_file?st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Tuning_of_emission_colours_in_strontium.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/48601963/Tuning_of_emission_colours_in_strontium_20160905-24091-1n93sxp-libre.pdf?1473131770=\u0026response-content-disposition=attachment%3B+filename%3DTuning_of_emission_colours_in_strontium.pdf\u0026Expires=1732510780\u0026Signature=Y9QOs6RHeG337pWE~cnDCb2IflPMIomXxEADHNt33jSvQjV34XwckPrl9CdpzDNHqQZP2mWygGO7NQkVDXFbcRU~Zo-7CsxF-zOVsxwtAFE2~-0csk~avMCYRvKKnYMXqS1TRkzieyqsQ0nqyxaX7tA370qnJBeKoaOuPQO0V2LmcZpXfAKWF4MXuPoOMbakuF7yLdwwUwP8HAoZVlR-ekokkaB8c2oQki-8FYgG-URiPNAdfbRWkTQWF4OeOevYzRGhDw2mRW2QUsHqLHnBxFmpw0CaX13cuIg-ZuiDY-jM8-tPlbrMm3cPBvUoRWiN0eo1U6teK3QU8PGs4GQLsg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Tuning_of_emission_colours_in_strontium_aluminate_long_persisting_phosphor","translated_slug":"","page_count":5,"language":"en","content_type":"Work","owner":{"id":12189830,"first_name":"Pooja","middle_initials":null,"last_name":"Sharma","page_name":"PoojaSharma71","domain_name":"independent","created_at":"2014-05-19T15:41:35.134-07:00","display_name":"Pooja Sharma","url":"https://independent.academia.edu/PoojaSharma71"},"attachments":[{"id":48601963,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/48601963/thumbnails/1.jpg","file_name":"Tuning_of_emission_colours_in_strontium_20160905-24091-1n93sxp.pdf","download_url":"https://www.academia.edu/attachments/48601963/download_file?st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Tuning_of_emission_colours_in_strontium.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/48601963/Tuning_of_emission_colours_in_strontium_20160905-24091-1n93sxp-libre.pdf?1473131770=\u0026response-content-disposition=attachment%3B+filename%3DTuning_of_emission_colours_in_strontium.pdf\u0026Expires=1732510780\u0026Signature=Y9QOs6RHeG337pWE~cnDCb2IflPMIomXxEADHNt33jSvQjV34XwckPrl9CdpzDNHqQZP2mWygGO7NQkVDXFbcRU~Zo-7CsxF-zOVsxwtAFE2~-0csk~avMCYRvKKnYMXqS1TRkzieyqsQ0nqyxaX7tA370qnJBeKoaOuPQO0V2LmcZpXfAKWF4MXuPoOMbakuF7yLdwwUwP8HAoZVlR-ekokkaB8c2oQki-8FYgG-URiPNAdfbRWkTQWF4OeOevYzRGhDw2mRW2QUsHqLHnBxFmpw0CaX13cuIg-ZuiDY-jM8-tPlbrMm3cPBvUoRWiN0eo1U6teK3QU8PGs4GQLsg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":48,"name":"Engineering","url":"https://www.academia.edu/Documents/in/Engineering"},{"id":10655,"name":"Scanning Electron Microscopy","url":"https://www.academia.edu/Documents/in/Scanning_Electron_Microscopy"},{"id":33912,"name":"Doping","url":"https://www.academia.edu/Documents/in/Doping"},{"id":35267,"name":"Photoluminescence","url":"https://www.academia.edu/Documents/in/Photoluminescence"},{"id":76714,"name":"Color","url":"https://www.academia.edu/Documents/in/Color"},{"id":118582,"name":"Physical sciences","url":"https://www.academia.edu/Documents/in/Physical_sciences"},{"id":186080,"name":"XRD","url":"https://www.academia.edu/Documents/in/XRD"},{"id":321836,"name":"Spectrum","url":"https://www.academia.edu/Documents/in/Spectrum"},{"id":395801,"name":"Rare Earth","url":"https://www.academia.edu/Documents/in/Rare_Earth"},{"id":566559,"name":"Stoichiometry","url":"https://www.academia.edu/Documents/in/Stoichiometry"},{"id":580255,"name":"Phosphors","url":"https://www.academia.edu/Documents/in/Phosphors"},{"id":902446,"name":"X Ray Diffraction Analysis","url":"https://www.academia.edu/Documents/in/X_Ray_Diffraction_Analysis"},{"id":973996,"name":"Process Parameters","url":"https://www.academia.edu/Documents/in/Process_Parameters"}],"urls":[{"id":2924020,"url":"http://dx.doi.org/10.1088/0022-3727/36/18/012"}]}, dispatcherData: dispatcherData });

The appropriate usage of H 3 BO 3 in defining the crystal structure, morphology and momentous variation in luminescent properties of calcium aluminate long persisting (LP) phosphor is systematically studied and presented. The results attribute two major roles for H 3 BO 3 ; as a flux for promoting the formation of required crystalline phase, when added in the amounts less than 10 mol% and as one of the precursors for the formation of aluminoborate complex when added above 10 mol%. This amount could be treated as a threshold for aluminoborate complex formation. Luminescent studies revealed that out of all phases identified, CaAl 2 O 4 is the only phase contributing for maximum photoluminescence (PL) augmentation and long persistence (10-12 h) from Eu 2+ and Nd 3+ ions, respectively. The relevant chemistry and reaction mechanism involved during solid-state synthesis of rare-earth doped calcium aluminate LP phosphor system have been discussed with greater emphasis on the luminescent properties affected with the addition of boric acid.","publication_date":{"day":null,"month":null,"year":2007,"errors":{}},"publication_name":"Materials Chemistry and Physics","grobid_abstract_attachment_id":48601946},"translated_abstract":null,"internal_url":"https://www.academia.edu/7095331/Role_of_boric_acid_in_synthesis_and_tailoring_the_properties_of_calcium_aluminate_phosphor","translated_internal_url":"","created_at":"2014-05-19T15:42:19.917-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":12189830,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":48601946,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/48601946/thumbnails/1.jpg","file_name":"Role_of_boric_acid_in_synthesis_and_tail20160905-1487-1ijf58c.pdf","download_url":"https://www.academia.edu/attachments/48601946/download_file?st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Role_of_boric_acid_in_synthesis_and_tail.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/48601946/Role_of_boric_acid_in_synthesis_and_tail20160905-1487-1ijf58c-libre.pdf?1473131771=\u0026response-content-disposition=attachment%3B+filename%3DRole_of_boric_acid_in_synthesis_and_tail.pdf\u0026Expires=1732510780\u0026Signature=b6vzcxd-ztVMu~FHuz3vfNHAotxcBU6Ym~KOgwj-2eCKudaH8d5xDpkRiBnH-V9ekfHHN14VENbGmkUxjX6VzxmYldZelUA-hEmP70S4iJW7gx6qbhjMicj5jQRHsY3lTbYHFmPBJCcUzWzz3swLMsBHpRwi84s8-PENwLKyLlt3JgPaG7KSUdMnJDpP20g~s-SrtYkyXc7TBzyhM72AwoVHyssQhBQMrmU7z5zjrPRCwaF29r8i1MxwXXYVXDDsVu6s4ALPv7xuy842g~sqFR9gzqftuiw~C-GSj38AsjSiKQs8EZgr4ihRB0rLPUAYSj9GQuHzvQLL4h3p~Gz8Rg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Role_of_boric_acid_in_synthesis_and_tailoring_the_properties_of_calcium_aluminate_phosphor","translated_slug":"","page_count":8,"language":"en","content_type":"Work","owner":{"id":12189830,"first_name":"Pooja","middle_initials":null,"last_name":"Sharma","page_name":"PoojaSharma71","domain_name":"independent","created_at":"2014-05-19T15:41:35.134-07:00","display_name":"Pooja Sharma","url":"https://independent.academia.edu/PoojaSharma71"},"attachments":[{"id":48601946,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/48601946/thumbnails/1.jpg","file_name":"Role_of_boric_acid_in_synthesis_and_tail20160905-1487-1ijf58c.pdf","download_url":"https://www.academia.edu/attachments/48601946/download_file?st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Role_of_boric_acid_in_synthesis_and_tail.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/48601946/Role_of_boric_acid_in_synthesis_and_tail20160905-1487-1ijf58c-libre.pdf?1473131771=\u0026response-content-disposition=attachment%3B+filename%3DRole_of_boric_acid_in_synthesis_and_tail.pdf\u0026Expires=1732510780\u0026Signature=b6vzcxd-ztVMu~FHuz3vfNHAotxcBU6Ym~KOgwj-2eCKudaH8d5xDpkRiBnH-V9ekfHHN14VENbGmkUxjX6VzxmYldZelUA-hEmP70S4iJW7gx6qbhjMicj5jQRHsY3lTbYHFmPBJCcUzWzz3swLMsBHpRwi84s8-PENwLKyLlt3JgPaG7KSUdMnJDpP20g~s-SrtYkyXc7TBzyhM72AwoVHyssQhBQMrmU7z5zjrPRCwaF29r8i1MxwXXYVXDDsVu6s4ALPv7xuy842g~sqFR9gzqftuiw~C-GSj38AsjSiKQs8EZgr4ihRB0rLPUAYSj9GQuHzvQLL4h3p~Gz8Rg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":56,"name":"Materials Engineering","url":"https://www.academia.edu/Documents/in/Materials_Engineering"},{"id":300,"name":"Mathematics","url":"https://www.academia.edu/Documents/in/Mathematics"},{"id":2305,"name":"Materials Chemistry","url":"https://www.academia.edu/Documents/in/Materials_Chemistry"},{"id":50630,"name":"Crystal structure","url":"https://www.academia.edu/Documents/in/Crystal_structure"},{"id":394500,"name":"Boric Acid","url":"https://www.academia.edu/Documents/in/Boric_Acid"},{"id":395801,"name":"Rare Earth","url":"https://www.academia.edu/Documents/in/Rare_Earth"},{"id":845691,"name":"Reaction Mechanism","url":"https://www.academia.edu/Documents/in/Reaction_Mechanism"}],"urls":[{"id":2924019,"url":"http://www.sciencedirect.com/science/article/pii/S0254058406001118"}]}, dispatcherData: dispatcherData });

The sample ®red in N 2 atmosphere with aluminum and bromine shows predominantly green emission with a peak around 530 nm whereas the sample prepared under H 2 S and HBr shows the broadest emission spectrum with multiple peaks. These peaks may arise out of different possible bands of copper, self-activated luminescence of ZnS and association of copper with some of the donor levels formed because of the higher reactivity of HBr. All the samples have been found to obey the relation B B 0 exp.(Àb/V 0.5 ) which has been discussed using bipolar tunnel emission model. The frequency variation of brightness is linear. Samples containing bromine show multiple secondary peaks indicating that bromine helps in formation of multiple shallow traps. #","publication_date":{"day":null,"month":null,"year":2003,"errors":{}},"publication_name":"Materials Research Bulletin","grobid_abstract_attachment_id":48601907},"translated_abstract":null,"internal_url":"https://www.academia.edu/7095330/Characterization_of_ZnS_Cu_Br_electroluminescent_phosphor_prepared_by_new_route","translated_internal_url":"","created_at":"2014-05-19T15:42:19.576-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":12189830,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":48601907,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/48601907/thumbnails/1.jpg","file_name":"Characterization_of_ZnSCu_Br_electrolumi20160905-24097-dy9u88.pdf","download_url":"https://www.academia.edu/attachments/48601907/download_file?st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Characterization_of_ZnS_Cu_Br_electrolum.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/48601907/Characterization_of_ZnSCu_Br_electrolumi20160905-24097-dy9u88-libre.pdf?1473131771=\u0026response-content-disposition=attachment%3B+filename%3DCharacterization_of_ZnS_Cu_Br_electrolum.pdf\u0026Expires=1732510780\u0026Signature=biDQqN~MHb0d-P-yehUVASn1Fcni0sk1mcY83nK7IK9YZlSvUWyL2Eq0blGzXtDIPhHrzQtrVLCPGNcV1M0FrN4cKVZu9iTuWKAHDPFVNXtEpuOGIsWu5zVCxlxVflA0E2RvilpEtAtEHWZqwQrUWe9fVXpUfYD2m8gozQqmHtr7opfHe3alO5AaG2PFheTWed82AtvbFsT1r2o4SeK~ep8ABLkEfcMMAL3H2k0y1iccbW-9TOJ~L3M5RCFUFimw8i6gWrWYqB1U3iaut~IjsJ9dmqG9HgptPFLDmKrp1eTDoyW6szfPrm-OnRkw50SqfkFA4Pm~sQcNtxFWwATb-g__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Characterization_of_ZnS_Cu_Br_electroluminescent_phosphor_prepared_by_new_route","translated_slug":"","page_count":10,"language":"en","content_type":"Work","owner":{"id":12189830,"first_name":"Pooja","middle_initials":null,"last_name":"Sharma","page_name":"PoojaSharma71","domain_name":"independent","created_at":"2014-05-19T15:41:35.134-07:00","display_name":"Pooja Sharma","url":"https://independent.academia.edu/PoojaSharma71"},"attachments":[{"id":48601907,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/48601907/thumbnails/1.jpg","file_name":"Characterization_of_ZnSCu_Br_electrolumi20160905-24097-dy9u88.pdf","download_url":"https://www.academia.edu/attachments/48601907/download_file?st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&st=MTczMjUwNzE4MCw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Characterization_of_ZnS_Cu_Br_electrolum.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/48601907/Characterization_of_ZnSCu_Br_electrolumi20160905-24097-dy9u88-libre.pdf?1473131771=\u0026response-content-disposition=attachment%3B+filename%3DCharacterization_of_ZnS_Cu_Br_electrolum.pdf\u0026Expires=1732510780\u0026Signature=biDQqN~MHb0d-P-yehUVASn1Fcni0sk1mcY83nK7IK9YZlSvUWyL2Eq0blGzXtDIPhHrzQtrVLCPGNcV1M0FrN4cKVZu9iTuWKAHDPFVNXtEpuOGIsWu5zVCxlxVflA0E2RvilpEtAtEHWZqwQrUWe9fVXpUfYD2m8gozQqmHtr7opfHe3alO5AaG2PFheTWed82AtvbFsT1r2o4SeK~ep8ABLkEfcMMAL3H2k0y1iccbW-9TOJ~L3M5RCFUFimw8i6gWrWYqB1U3iaut~IjsJ9dmqG9HgptPFLDmKrp1eTDoyW6szfPrm-OnRkw50SqfkFA4Pm~sQcNtxFWwATb-g__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":56,"name":"Materials Engineering","url":"https://www.academia.edu/Documents/in/Materials_Engineering"},{"id":10650,"name":"Materials","url":"https://www.academia.edu/Documents/in/Materials"},{"id":14925,"name":"Heat Treatment","url":"https://www.academia.edu/Documents/in/Heat_Treatment"},{"id":32910,"name":"Sample Preparation","url":"https://www.academia.edu/Documents/in/Sample_Preparation"},{"id":33912,"name":"Doping","url":"https://www.academia.edu/Documents/in/Doping"},{"id":80692,"name":"Copper","url":"https://www.academia.edu/Documents/in/Copper"},{"id":158914,"name":"Luminescence","url":"https://www.academia.edu/Documents/in/Luminescence"},{"id":321836,"name":"Spectrum","url":"https://www.academia.edu/Documents/in/Spectrum"},{"id":991011,"name":"Electroluminescence","url":"https://www.academia.edu/Documents/in/Electroluminescence"},{"id":1152821,"name":"Chemical Synthesis","url":"https://www.academia.edu/Documents/in/Chemical_Synthesis"},{"id":2217031,"name":"Spectral Energy Distribution","url":"https://www.academia.edu/Documents/in/Spectral_Energy_Distribution"}],"urls":[{"id":2924018,"url":"http://www.sciencedirect.com/science/article/pii/S0025540802010279"}]}, dispatcherData: dispatcherData });

The dependence of initial brightness and observed afterglow characteristics on various thermal processing parameters such as heating rates, time of constant heating and cooling rates have been investigated. It has been found that heating rates (\u003e625 • C h −1 ), time of constant heating (\u003c2 h at around 1200 • C) and cooling rates (\u003e250 • C h −1 ) resulted in non-uniform luminescent samples which are not excited under roomlight but under UV (365 nm). Whereas heating rates (\u003c300 • C h −1 ), time of constant heating (\u003e4 h at 1200 • C) and cooling rates (\u003c100 • C h −1 ) resulted in high-density ceramic compact (∼3100 kg m −3 ) samples with very low initial brightness but quite long afterglow under roomlight and UV excitation. An optimum of both fast rise and long afterglow under roomlight excitation has been achieved for the SRA samples fired with the heating rates of 300-625 • C h −1 , time of constant heating 2-4 h at around 1200 • C and cooling rates of 100-250 • C h −1 .
