摘要：
Disclosed are oxynitride phosphor compositions having the formula (RE1-xCex)3Ala-y-z-wSiyGazScwO12-yNy, where RE is at least one of Lu, Gd, Y, and Tb, 0.001≦x≦0.10, 0≦w≦2, 0.001≦y≦0.50, 0≦z≦4.999, and 4.5≦a≦5.0. When combined with radiation from a blue or UV LED, these phosphors can provide light sources with good color quality having high CRI over a large color temperature range. Also disclosed are blends of the above oxynitride phosphors and additional phosphors.
