| 发明名称 | Oxynitride phosphor powder | ||
| 摘要 | An oxynitride phosphor power has a fluorescence peak wavelength of 580 to 605 nm, the oxynitride phosphor having a higher external quantum efficiency than ever before. The oxynitride phosphor powder is an oxynitride phosphor powder containing α-SiAlON and aluminum nitride, represented by composition formula: Cax1Eux2Si12−(y+z)Al(y+z)OzN16−z wherein x1, x2, y and z are 0<x1≦2.50, 0.01≦x2≦0.20, 0<y≦2.3 and 1.5≦z≦3.5, or x1, x2, y and z are 0<x1≦2.70, 0.05≦x2≦0.20, 2.3≦y≦5.5 and 1≦z≦2.5. | ||
