Cerium Based Phosphor Materials for Improved Light Quality in LEDs

Researchers at the University of California Santa Barbara have discovered a novel luminescent cerium compound that emits bright red light when used as a phosphor. This compound can be applied to enhance the light quality of systems using a blue LED with a yellow/green phosphor. It can also be utilized as the red phosphor in a system using a UV LED and RGB phosphors. Due to the chemical makeup there is a decrease of the emission wavelength towards the yellow/orange region and thus it can be used directly as the yellow phosphor with a blue LED. This technology is available for licensing.
