New Materials Could Bring More Natural Lighting from LEDs

Scientists from Oak Ridge and Argonne national labs and the University of Georgia are working together to develop a new group of phosphors that glow in a broader part of the electromagnetic spectrum. They are growing and testing nanocrystals composed of europium oxide and aluminum oxide powders. Europium is a rare-earth element that has exceptional phosphorescent qualities. Making a LED bulb that produces warm, white light is still the goal.
