With enhanced electrical and optical properties, quantum dots are the cutting-edge of nanotechnology. Features and Applications When excited, these materials confine electrons and holes. The smaller the dot, the greater the confinement energy, leading to higher energy absorption and emission. This means more efficient photon management for your applications. Our selection of quantum dots guarantees high purity with properties including, chemical inertness, high tolerance, or low toxicity. Quantum dots find use in a wide range of applications. With good biocompatibility, they are ideal for drug delivery and bioimaging; or with excellent photoluminescent quantum yields, they have huge potentials in solar cells and LED displays.

With enhanced electrical and optical properties, quantum dots are the cutting-edge of nanotechnology.</p> <h2 class="h3">Features and Applications</h2> <ul> <li>When excited, these materials confine electrons and holes. The smaller the dot, the greater the confinement energy, leading to higher energy absorption and emission. This means more efficient photon management for your applications.</li> <li>Our selection of quantum dots guarantees high purity with properties including, chemical inertness, high tolerance, or low toxicity.</li> <li>Quantum dots find use in a wide range of applications.

When Sony launched their XBR line of televisions in 2013, quantum dots successfully moved from pure research into the commercial sphere. Despite this, there are still some barriers to overcome before we can expect to see widespread adoption of quantum dot-based products.</p> <a href="/blogs/articles/perovskite-quantum-dots-rapidly-expanding-area-of-research">Read more...</a> </div> </div> <div class="col-xs-12 col-sm-6 button-col"> <div class="card-box card-truncate"> <a href="/pages/what-is-molecular-engineering?"><img alt="molecular engineering" height="160" loading="lazy" src="https://www.ossila.com/cdn/shop/files/molecular_synthesis.jpg?v=1722237845&crop=left&width=160&height=160"></a> <a href="/pages/what-is-molecular-engineering">What is molecular engineering?</a> <p>Molecular engineering is simply the design and synthesis of molecules with specific properties and functions in mind.

These are based on semiconductors such as cadmium selenide, indium phosphide or lead(II) sulfide. The bandgap of such quantum dots can be tuned throughout the entire visible spectrum simply by changing their size during chemical synthesis.</p> <p>For the highest photoluminescence quantum yields (PLQY), a shell structure is usually required. In this arrangement, a second semiconductor encapsulates the nanocrystal. This material passivates surface defects of the emissive core which would otherwise act as non-radiative recombination sites for excitons.</p> <p>Due to their high PLQY, relative ease of fabrication and wide emission-colour tunability, quantum dots having this type of structure are especially suitable for display and imaging technologies. Already, you can find them in commercial products such as televisions.</p> </div> </div> </main> </div> <!-- Begin Sidebar Left Content --> <aside id="sidebar-left" class="col-sm-3 col-md-2 col-sm-pull-9 col-md-pull-8 no-padding sidebar"> <div class="col-xs-12 no-padding"> <section> <div id="sidebar-trust-ossila"> <a href="/pages/about"> <div class="alert-sidebar alert-sidebar-title"> The Ossila Guarantee </div> <div class="alert-sidebar alert-sidebar-content text-left"> <div id="alert-sidebar-clipboard-box-guarantee" class="alert-sidebar-product-or-guide-box alert-sidebar-clipboard-box"> <ul><li>Worldwide Shipping</li><li>Fast Secure Dispatch</li><li>Quality Assured</li><li>Clear Upfront Pricing</li><li>Large Order Discounts</li><li>Expert Support</li></ul> <p class="text-small hyperlink-style">Read more...</p> </div> <div class="alert-sidebar-clipboard-image"><img width="35" height="35" src="//www.ossila.com/cdn/shop/t/303/assets/sidebar-blue-tick.svg?v=17164661526435590041729065669" alt="The Ossila Guarantee" loading="lazy" /></div> </div> </a> </div> </section> </div> <div class="col-xs-12 no-padding"> <section> <div id="sidebar-testimonials"> <a href="/pages/awards-and-testimonials"> <div class="alert-sidebar alert-sidebar-title"> Trusted Worldwide </div> <div class="alert-sidebar alert-sidebar-content text-left"> <div id="alert-sidebar-clipboard-box-social-proof" class="alert-sidebar-product-or-guide-box alert-sidebar-clipboard-box"> <!-- randomNumber is: 9 --> <img loading="lazy" width="159" height="66" src=" https://www.ossila.com/cdn/shop/files/uni-adelaide-logo-compact.png" alt="Testimonial by Roziana Abdullah" /><!--style="width:159px"--> </div> <div id="alert-sidebar-clipboard-box-social-proof-text"> <p><span class="sidebar-testimonials-quote-marks">"</span><i>I greatly appreciate your website for giving such a clear and detailed explanation of spin coating theory.
