Novel Rare Earth Element-Free Lighting Phosphors with High Quantum Efficiency and Enhanced Thermal and Photostability
​ ​ Invention Summary: Light-emitting diodes (LEDs), the main branch of solid-state-lighting (SSL) technology, are rapidly replacing conventional lighting sources because they are much more energy-efficient and longer-lasting. However, current LED devices rely heavily on rare-earth elements, which are in severe cost and supply risk in addition...
