摘要
Disclosed are phosphor compositions having the formulas CaSUB1-a-b/SUBCeSUBa/SUBEuSUBb/SUBAlSUB1+a/SUBSiSUB1-a/SUBNSUB3/SUB, where 0a=0.2, 0=B=0.2; CASUB1-c-d/SUBCeSUBc/SUBEuSUBd/SUBAlSUB1-c/SUB(Mg,Zn)SUBc/SUBSiNSUB3/SUB, where 0c=0.2, 0=D=0.2; CASUB1-2e-f/SUBCeSUBe/SUB(Li,Na)SUBe/SUBEuSUBf/SUBAlSiNSUB3/SUB, where 0=e=0.2, 0=f=0.2, g+h0; and CaSUB1-g-h-i/SUBCeSUBg/SUB(Li,Na)SUBh/SUBEuSUBi/SUBAlSUB1+g-h/SUBSiSUB1-g+h/SUBNSUB3 /SUBwhere 0=g=0.2, 0h=0.4, 0=i=0.2,g+i0. When combined with radiation from a blue or UV light source, 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 phosphors and additional phosphors.
