PROBLEM TO BE SOLVED: To provide a method for producing a silicate phosphor having high luminance and to provide the phosphor produced by the method for production. SOLUTION: The method for producing the silicate phosphor comprises firing a mixture of metal compounds. In the method, a spherical silicon oxide is used as one of the metal compounds. The silicate phosphor comprises a compound represented by general formula mM<SP>1</SP>O-nM<SP>2</SP>O-2SiO<SB>2</SB>(wherein, M<SP>1</SP>is one or more selected from the group consisting of Ca, Sr and Ba; M<SP>2</SP>is one or more selected from the group consisting of Mg and Zn; m is≥0.5 and≤3.5; and n is≥0.5 and≤2.5) and one or more selected from the group consisting of Eu and Mn as an activator. The silicate phosphor is obtained by the method for production described in any thereof and contains≥80 wt.% of particles having≤5μm primary particle diameter. COPYRIGHT: (C)2004,JPO
