METHOD FOR PRODUCING BETA-SIALON FLUORESCENT MATERIAL |
| 摘要 |
A method for producing a β-sialon fluorescent material superior in light emitting luminance is provided. The method includes heat-treating a first mixture containing an aluminum compound, a europium compound, and a first silicon oxynitride compound to obtain a first heat-treated product, and heat-treating a second mixture containing the first heat-treated product, an aluminum compound, a europium compound, and a second silicon oxynitride compound, which has a larger oxygen content than the first silicon oxynitride compound, to obtain a second heat-treated product. |

1. A method for producing a β-sialon fluorescent material, the method comprising:
heat-treating a first mixture containing an aluminum compound, a europium compound, and a first silicon oxynitride compound to obtain a first heat-treated product; and heat-treating a second mixture containing the first heat-treated product, an aluminum compound, a europium compound, and a second silicon oxynitride compound, which has an oxygen content larger than an oxygen content in the first silicon oxynitride compound, to obtain a second heat-treated product. |
