Abstract

　Ｍ1、Ｍ2、Ｍ3、Ｍ4、ハロゲン元素およびＯからなる蛍光体（ここで、Ｍ1はアルカリ土類金属元素を表わし、Ｍ2は３価の金属元素を表わし、Ｍ3は付活元素を表わし、Ｍ4は４価の金属元素を表わす。）であって、Ｍ1：（Ｍ2＋Ｍ3）：Ｍ4：ハロゲン元素のモル比が、１：４：３：ａ（ここで、ａは０．０１以上３以下の範囲の値である。）である高い発光輝度を有する蛍光体を提供する。かかる蛍光体はＭ1、Ｍ2、Ｍ3、Ｍ4およびハロゲン元素を含有する金属化合物混合物（ここで、Ｍ1、Ｍ2、Ｍ3、Ｍ4は前記と同じ意味を有する。）であって、Ｍ1のハロゲン化物、Ｍ2のハロゲン化物およびＭ3のハロゲン化物からなる群から選ばれる１種以上のハロゲン化物を含有する金属化合物混合物を焼成して得ることができる。
