| titleOfInvention | Acid nitride phosphor powder and method for producing same |
| abstract | An oxynitride phosphor having a higher external quantum efficiency than the conventional one is provided for an oxynitride phosphor having a fluorescence peak wavelength of 587 to 630 nm. In the present invention, a silicon nitride powder, a substance serving as an aluminum source, a substance serving as a calcium source, and a substance serving as a europium source are mixed, and fired at 1500 to 2000 ° C. in an inert gas atmosphere or a reducing gas atmosphere to produce an intermediate. After obtaining an oxynitride phosphor fired product having Ca-containing α-sialon as a main component, the oxynitride phosphor fired product is further calcined at 1450 ° C. to the above fired in an inert gas atmosphere or a reducing gas atmosphere under conditions in which Li is present. The present invention relates to a method for producing an oxynitride phosphor powder containing 50 to 10,000 ppm of Li, characterized by heat treatment at a temperature below the temperature. |
