Disclosed are phosphor compositions having the formula (RE<SUB>1-y</SUB>Ce<SUB>y</SUB>)Mg<SUB>2-x</SUB>Li<SUB>x</SUB>Si<SUB>3-x</SUB>P<SUB>x</SUB>O<SUB>12</SUB>, where RE is at least one of Sc, Lu, Gd, Y, and Tb, 0.0001<x<0.1 and 0.001<y<0.1. When combined with at least one additional phosphor and subjected to radiation from a blue or UV LED, these phosphors can provide white light sources with good color quality having high CRI over a large color temperature range. Also disclosed are blends of the above phosphors and additional phosphors.
