A phosphor composition comprising a solid solution of aluminum nitride and a complex oxide comprising europium and strontium, wherein an amount of oxygen in the solid solution is at least 0.4 weight percent and less than 1 weight percent.
A phosphor composition derived from:
- combining aluminum nitride, europium oxide and strontium carbonate, wherein an amount of a combination of europium oxide and strontium carbonate is in a range of from about 5 weight percent to about 10 weight percent, based on an amount of aluminum nitride;
- and
- firing the combination.
