International Classification:
G09K 1156
US Classification:
2523016S
Abstract:
An orange-yellow-emitting zinc sulfide-based electroluminescent phosphor is described wherein the phosphor has a brightness of greater than 10 foot-Lamberts. More particularly, the phosphor has a brightness of at least about 13 foot-Lamberts and an x color coordinate from about 0. 51 to about 0. 56 and a y color coordinate from about 0. 42 to about 0. 48. The zinc sulfide phosphor is activated with manganese, copper, chlorine, and a metal selected from gold and antimony.
