ABSTRACT:
Phosphor compositions having the formula (Ba,Sr,Ca)SiO4:Eu and light emitting devices including a semiconductor light source and the above phosphor. Also disclosed are blends of (Ba,Sr,Ca)SiO4:Eu and one or more additional phosphors and light emitting devices incorporating the same. Preferred blends include (Sr,Ba,Ca)2SiO4:Eu and at least one of (Sr,Mg,Ca,Ba,Zn)2P2O7:Eu,Mn; (Ca,Sr,Ba,Mg)5(PO4)3(Cl,F,OH):Eu,Mn; (Sr,Ba,Ca)MgAl10O17:Eu,Mn; and Mg4FGeO6:Mn4+; and one or more garnet phosphors having the general formula (Y,Gd,La,Lu,T,Pr,Sm)3(Al,Ga,In)5O12:Ce.
