    • 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.
    • 本发明提供了可以提高发光强度而不添加除了组成“ial”型赛隆荧光物质的元素以外的金属元素的“ial”型赛隆荧光物质的制造方法。 也就是说,在氮化物或氮化物的晶体中含有作为发光中心的光学活性元素的荧光物质的制造方法中,通过对包括 金属化合物粉末和光学活性元素化合物; 用于在氮气氛下冷却后对烧成品进行热处理的高温退火处理; 在稀有气体气氛下对高温退火产品进行热处理的稀有气体退火工艺; 以及用酸处理稀有气体处理产物的方法。
