ABSTRACT:
A system includes a radiation source capable of emitting first light and a fluorescent material capable of absorbing the first light and emitting second light having a different wavelength than the first light. The fluorescent material is a phosphor having the formula (Lu1-x-y-a-bYxGdy)3(Al1-zGaz)5O12:CeaPrbwherein 0<x<1, 0<y<1, 0<z≦0.1, 0<a≦0.2 and 0<b≦0.1. In some embodiments, the (Lu1-x-y-a-bYxGdy)3(Al1-zGaz)5O12:CeaPrbis combined with a second fluorescent material capable of emitting third light. The second fluorescent material may be a red-emitting phosphor, such that the combination of first, second, and third light emitted from the system appears white.
