| titleOfInvention | Oxynitride phosphor powder and method for producing the same |
| abstract | Provided is an oxynitride phosphor powder composed of an α-sialon phosphor having a fluorescence peak wavelength of 605 to 615 nm, and having an external quantum efficiency higher than that of the prior art. The oxynitride phosphor powder of the present invention has a composition formula: Ca x1 Eu x2 Si 12- (y + z) Al (y + z) O z N 16-z (wherein x1, x2, y, z are 1 .10 ≦ x1 + x2 ≦ 1.70, 0.18 ≦ x2 / x1 ≦ 0.47, 2.6 ≦ y ≦ 3.6, 0.0 ≦ z ≦ 1.0) . Furthermore, an oxynitride phosphor powder made of α-sialon containing 50 to 10,000 ppm of Li is also provided. In addition, the present invention relates to a method for producing these oxynitride phosphor powders, and the raw material silicon source material has an oxygen content of 0.2 to 0.9 mass% and an average particle size of 1. A silicon nitride powder having a specific surface area of 0.2 to 3.0 m 2 / g is preferable. |
