| titleOfInvention | Phosphor, and light-emitting device and use thereof |
| abstract | The purpose of the present invention is to provide: a phosphor which can be combined with a blue LED to emit white light having a low color temperature as in the case where the phosphor is used singly, has a broad fluorescence spectrum that is advantageous for achieving high color rendering properties, has high light emission efficiency, has thermal/chemical stability that is characteristic for conventional nitride phosphors, and rarely undergoes the deterioration in brightness at higher temperatures; and a light-emitting device which is equipped with the phosphor. The phosphor is represented by the general formula: Mx(Si,Al)2(N,O)3+-y (wherein M's independently represent Li or at least one alkali earth metal element; and x and y fulfill the requirement represented by the formulae: 0.52 <= x <= 0.9 and 0 <= y <= 0.3) wherein some of M's are substituted by element Ce, and wherein the Si/Al atomic ratio is 1.5 to 6 inclusive, the O/N atomic ratio is 0 to 0.1 inclusive, 5-50 mol% of M's is Li, and 0.5-10 mol% of M's is Ce. |
