There is herein described a phosphor for use in LED applications and particularly in phosphor-conversion LEDs (pc-LEDs). The phosphor has a composition represented by (Y1-xCex)3(Al1-yScy)5O12 wherein 0<x≦̸0.04 and 0<y≦̸0.6 and can be as applied to an LED as a transparent sintered ceramic or used in a powder form. By adjusting the composition of the phosphor, the phosphor can be made to emit light in the green to yellow regions of the visible spectrum upon excitation by a blue-emitting InGaN LED. |
