Abstract

　一般式：（ＣａＸ、ＥｕＹ）（Ｓｉ、Ａｌ）１２（Ｏ、Ｎ）１６（但し、１．５＜Ｘ＋Ｙ＜２．２、かつ０＜Ｙ＜０．２、Ｏ／Ｎ≦０．０４）で示されるα型サイアロンを主成分とする蛍光体の製造方法するに際し、原料粉末として、（ａ）窒化ケイ素と、（ｂ）窒化アルミニウムと、（ｃ）Ｃａ含有化合物と、（ｄ）Ｅｕ含有化合物と、（ｅ）α型サイアロンとを用い、原料混合粉末を窒素雰囲気中、１６５０～１８５０°Cで加熱処理することによりα型サイアロンを得る。加熱処理後の粉末を粉砕することなく分級処理することにより、平均粒径が１５～２５μｍの粉末を得る。これにより、発光効率に優れ、５９５ｎｍ以上の波長にピークを有する高窒素含有率のα型サイアロン蛍光体を提供する。
