The project “Chiral Light-Emitting Diodes Based on Photonic Architectures” (RADIANT) received €3.6 million in funding from the European Union’s EIC Pathfinder Horizon programme in 2024. Its goal is to develop cost-effective, high-performance chiral LEDs that exploit the optical properties of scalable chiral metasurfaces, operating optimally in the visible to near-infrared spectrum. The results could be applied to fields such as display technology, optical communication, remote sensing, and advanced lighting systems.
By leveraging the unique chiral response of chiral metasurfaces, RADIANT precisely modulates high photoluminescence quantum yield (PLQY) quantum emitters such as perovskite nanocrystals, quantum dots, and organic semiconductors through advanced nanophotonic architectures that interact with light via optical resonances, enhancing and tuning light emission.
RADIANT harnesses the potential of nanophotonics for optoelectronic technologies through cost-effective, scalable chiral metasurfaces produced by soft nanolithography, while reducing dependence on critical raw materials currently used in advanced LEDs. This will revolutionize the multi-billion-euro LED display market by combining technological innovation, economic feasibility and environmental sustainability.
The project is coordinated by Spain’s State Agency of the Spanish National Research Council (CSIC), specifically the Institute of Materials Science of Barcelona (ICMAB-CSIC). It began at the end of 2024 and also involves the universities of Vigo and Valencia; Lund University in Sweden; the Fondazione Istituto Italiano di Tecnologia in Italy; and the Spanish company Zirka Innotech, S.L.
