A red-emitting strontium-calcium sulfide phosphor doped with europium and a halide. These phosphors are made by combining their insoluble sulfates, adding europium as an activator, firing in hydrogen sulfide to form the corresponding sulfides, adding a halide co-activator and firing in nitrogen. The resulting phosphors can be used with various electroluminescent devices to produce colored or white light.
