Title: Phosphors for LED lamps

Abstract

A phosphor, a phosphor blend including the phosphor, a phosphor prepared by a process, and a lighting apparatus including the phosphor blend are disclosed. The phosphor has the formula (Ca.sub.1-p-qCe.sub.pK.sub.q).sub.xSc.sub.y(Si.sub.1-rGa.sub.r).sub.zO.su- b.12+.delta. or derived from a process followed using disclosed amounts of reactants. In the formula, (0<p.ltoreq.0.06); 0.ltoreq.q.ltoreq.0.06; 0.ltoreq.r.ltoreq.0.2; and -0.1.ltoreq..delta..ltoreq.0.4. In one embodiment, 3<x.ltoreq.3.1; 2.ltoreq.y.ltoreq.2.15; and 3.ltoreq.z.ltoreq.3.2. Similarly, in another embodiment, 3.ltoreq.x.ltoreq.3.1; 2<y.ltoreq.2.15; and 2.8.ltoreq.z.ltoreq.3.2.
