Current LED technology faces high costs, limited performance, and environmental impact. Traditional LEDs often lack the advanced optical properties required for next-generation applications, such as high brightness and efficient circular polarization. Furthermore, production processes are resource-intensive and heavily dependent on essential raw materials. In this context, the EIC-funded RADIANT project is designed to address these challenges. Specifically, it seeks to revolutionize LED technology by developing chiral LEDs using scalable chiral metasurfaces.
These LEDs promise improved performance, including superior brightness and circular polarization, while being cost-effective and environmentally sustainable. By integrating advanced nanophotonic architectures and a novel soft nanoimprinting process, RADIANT is poised to transform diverse industries, from display technology to sensing.
The project is based on a novel, scalable, low-carbon, soft nanoimprinting process that enables the seamless integration of photonic nanostructures into different LED technologies across a wide spectral range.
RADIANT (Chiral Light-Emitting Diodes based on Photonic Architectures) is a groundbreaking research effort with a transformative mission: the production of cost-effective, high-performance chiral LEDs (light-emitting diodes) that leverage the optical properties of scalable chiral metasurfaces, operating seamlessly across the visible to near-infrared spectrum.
Taking a multifaceted approach, the project seeks to endow three distinct technologies with chirality: organic light-emitting diodes (OLEDs), perovskite LEDs (PeLEDs), and quantum dot LEDs (QdotLEDs), which promise exceptionally bright output and remarkable degrees of circular polarization. These chiral LEDs find diverse applications in fields such as display technology, communications, sensing, and advanced lighting systems, and promise to revolutionize various industries with their enhanced optical properties and broad spectral range.
By leveraging the unique chiroptical response of chiral metasurfaces, RADIANT precisely modulates high photoluminescence quantum yield (PLQY) emitters, including perovskite nanocrystals, quantum dots, and organic semiconductors, using advanced nanophotonic architectures that interact with light through optical resonances, thereby enhancing and modulating light emission.
At the heart of the project is a novel, scalable, low-carbon soft nanoimprint printing process that enables the seamless integration of photonic nanostructures across different LED technologies over a wide spectral range. RADIANT unleashes the potential of nanophotonics for optoelectronic technologies through scalable and cost-effective chiral metasurfaces produced using soft nanoimprint lithography, while reducing reliance on critical raw materials currently used in advanced LEDs. RADIANT promises to revolutionize the multi-billion-dollar LED landscape market, combining technological innovation, economic viability, and environmental sustainability.
