PHOSPHOR |
| 摘要 |
According to one embodiment, the phosphor exhibits a luminescence peak within a wavelength range of 500 to 600 nm when it is excited with light having an emission peak within a wavelength range of 250 to 500 nm. The phosphor has a composition represented by (M1-xCex)2yAlzSi10-zOuNwBs (M represents Sr and a part of Sr may be substituted by at least one selected from the group consisting of Ba, Ca and Mg; and x, y, z, u, w and s satisfy 0<x≦1, 0.8≦y≦1.1, 2≦z≦3.5, 1<u≦1, 1.5≦z−u, 13≦u+w≦15, and 0<s<0.245.) |
