Red Phosphor Heightens White LEDs

Facebook X LinkedIn Email
A new material could help LEDs produce more pleasing white light. A team from Ludwig Maximilian University of Munich (LMU), in collaboration with Philips Technologie in Aachen, Germany, has developed a new red phosphor material based on the nitride Sr[LiAl3N4]. When doped with europium, it displays intense luminescence over a narrow range of frequencies in the red band. Peak emission occurs at wavelengths of around 650 nm, the researchers said, and peak width is 50 nm. The new red phosphor material can improve the color rendering for white LEDs.
