RADIANT · Chiral Light Emitting Diodes based in Photonic Architectures

RADIANT (Chiral Light Emitting Diodes based in Photonic Architectures) is an innovative research endeavor with a transformative mission: the production of high-performing and cost-efficient chiral LEDs (light-emitting diodes) that harness the optical properties of scalable chiral metasurfaces, operating seamlessly across the visible to near-infrared spectrum. With a multifaceted approach, the project seeks to endow with chirality three distinct technologies: Organic Light Emitting Diodes (OLEDs), Perovskite LEDs (PeLEDs), and Quantum Dot LEDs (QdotLEDs), promising 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, promising to revolutionize various industries with their enhanced optical properties and broad spectral range. 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 the light emission. At the core of the project lies a novel, scalable, and low carbon footprint soft nanoimprinting imprinting process that enables seamless integration of photonic nanostructures across different LED technologies in a broad spectral range. RADIANT unlocks the potential of nanophotonics for optoelectronic technologies through cost-effective and scalable chiral metasurfaces produced via soft nanoimprinting lithography while reducing the dependency on critical raw materials currently used in advanced LEDs. RADIANT promises to revolutionize the billionaire LED landscape market, combining technological innovation, economic viability, and environmental sustainability.
