Abstract:
Disclosed herein is a novel group of carbonitride and carbidonitride phosphors and light emitting devices which utilize these phosphors. In certain embodiments, the inventive phosphors are expressed as follows: Cam/2Si12-(m+n)−xCxAlm+nN16-nOnEu2+ (1) M(II)m/2Si12-(m+n)−xCxM(III)m+nN16-nOn-y/2Hy:A (2) Mm/vSi12-(m+n)−xCxM(III)m+nN16-nOn-y/2Hy:A (3) Cam/2Si12-(m+n)+xAlm+n−xN16-n−xCxOn:Eu2+ (4) M(II)m/2Si12-(m+n)+xM(III)m+n−xN16-n−xCxOn-y/2Hy:A (5) Mm/vSi12-(m+n)+xM(III)m+n−xN16-n−xCxOn-y/2Hy:A (6) wherein v is the valence number of M, 0≦m
