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<5, 0≦̸n≦̸3, 0≦̸x<4, and 0≦̸y<1, M is at least one cation, M(II) is at least one divalent cation, M(III) is at least one trivalent cation, H is at least one monovalent anion, and A is a luminescence activator. |
