Process for producing beta-sialon fluorescent material |
| abstract |
Provided is a production method of a β-type sialon fluorescent substance, where luminescence intensity can be improved without adding a metal element other than elements composing a β-type sialon fluorescent substance. Namely, in a production method of a fluorescent substance containing an optically-active element as the luminescence center in a crystal of nitride or acid nitride, a β-type sialon fluorescent substance is produced by a burning process for heat-treating a mixture including metal compound powder and an optically-active element compound; a high-temperature annealing process for heat-treating the burned product after cooling under a nitrogen atmosphere; a rare-gas annealing process for heat-treating the high-temperature annealed product under a rare gas atmosphere; and a process for treating the rare-gas treated product with an acid. |
