CARBONITRIDE BASED PHOSPHORS AND LIGHT EMITTING DEVICES USING THE SAME |
| 摘要 |
Disclosed herein is a novel group of carbonitride phosphors and light emitting devices which utilize these phosphors. In certain embodiments, the present invention is directed to a novel family of carbonitride-based phosphors expressed as follows: (1) Ca1-?Alx-xySi1-?+?yN2-x-?yCxy:A; (2) Ca1-x-zNazM(III)x-xy-zSi1-x+?y+zN2-?-?yCxy:A; (3) M(II)1-x-zM(I)zM(III)x-xy-zSi1-x+xy+zN2-x-xyCxy:A; (4) M(II)1-x-zM(I)zM(III)x-xy-zSi1-x+xy+zN2-x-xy-2w/3CxyOw-v/2Hv:A; and (4a) M(II)1-x-zM(I)zM(III)x-xy-zSi1-x+xy+zN2-x-xy-2w/3-v/3CxyOwHv:A, wherein 0<x<l, 0<y<l, 0 <z<l, 0 <v<l, 0<w<l, x+z<l, x>xy+z, and 0<x-xy-z<l, 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. |
