Lighting is a major source of energy consumption and the introduction of LEDs has been a game changer to reduce electrical consumption. Nanocrystal-based LEDs (QLEDs) have reached a high level of maturity with their use as light source in displays. In the infrared, there is currently a technological gap between 1.5 and 4 µm with very few sources available. Within BRIGHT, we aim to design infrared emitting QLEDs with enhanced light-matter coupling to address emission from 1 to 3 µm. Our strategy aims to couple the nanocrystals to optical resonators to achieve enhanced light extraction, which remains so far a key limitation of OLEDs and nanocrystal-based LEDs. Not only this spectral range (>2 µm) has never been addressed using nanocrystals, but the second challenge relates to the design of structure combing electrical transport with a nanophotonic structure. This project can find applications in gas spectroscopy, airfield lighting and industrial vision.
