Summary:
Since 2013 zero-dimensional, spherical quantum dots (QDs) are used by the display industry for high-end devices with improved color gamut compared to non-QD LED TVs. So a product based on QDs can be found in many private households already. However, QDs have more to give than just color conversion in LED TVs. Displays based on electroluminescence of QDs were already shown by Samsung on various trade shows, so their appearance on the market will not be far. Besides display, QDs can foster innovations in many other sectors as their unique properties allow many innovative ways of usage. In this talk we will start with an introduction about what QDs are, how they are made and which properties they exhibit. Afterwards we will summarize the newest progress in their applications not only in displays, but also in other fields like sensors, lighting, anti-counterfeiting and live sciences. We will show examples for electroluminescence, special lighting solutions, SWIR sensors, biomarkers and a special barcode system all based on QD technology which were developed in our labs. With this talk we hope that we can introduce you to the power of QD technology and help you to think about innovative products in our field of application. The pioneers of QDs were honored with the Nobel prize in chemistry in 2023. Now it’s for the next wave of novel applications powered by quantum effects.
