Carbonitride based phosphors and light emitting devices using the same
Abstract
Disclosed herein is a novel group of carbidonitride phosphors and light emitting devices which utilize these phosphors. In certain embodiments, the present invention is directed to a novel family of carbidonitridebased phosphors expressed as follows: Ca.sub.1xAl.sub.xxySi.sub.1x+xyN.sub.2xxyC.sub.xy:A; (1) Ca.sub.1xzNa.sub.zM(III).sub.xxyzSi.sub.1x+xy+zN.sub.2xxyC.sub.xy: A; (2) M(II).sub.1xzM(I).sub.zM(III).sub.xxyzSi.sub.1x+xy+zN.sub.2x xyC.sub.xy:A; (3) M(II).sub.1xzM(I).sub.zM(III).sub.xxyzSi.sub.1x+xy+zN.sub.2xxy2w/ 3C.sub.xyO.sub.wv/2H.sub.v:A; and (4) M(II).sub.1xzM(I).sub.zM(III).sub.xxyzSi.sub.1x+xy+zN.sub.2xxy2w/ 3v/3C.sub.xyO.sub.wH.sub.v:A, (4a) wherein 0<x<1, 0<y<1, 0.ltoreq.z<1, 0.ltoreq.v<1, 0<w<1, x+z<1, x>xy+z, and 0<xxyz<1, M(II) is at least one divalent cation, M(I) is at least one monovalent cation, M(III) is at least one trivalent cation, H is at least one monovalent anion, and A is a luminescence activator doped in the crystal structure.
