Fluorescent material, light emitting device, and method for producing fluorescent material

Abstract

A method for producing a fluorescent material is provided. The method includes preparing fluorescent material particles that contain an alkaline earth metal aluminate having a composition represented by (Sr1−x,Eux)4Al14O25, where x satisfies 0.05≦x≦0.4, and a part of Sr may be substituted by at least one element selected from the group consisting of Mg, Ca, Ba, and Zn; causing the prepared fluorescent material particles to come into contact with a liquid medium containing water; removing at least a portion of the contacted liquid medium to obtain purified fluorescent material particles; causing a phosphate compound to adhere to surfaces of the purified fluorescent material particles to obtain fluorescent material particles to which the phosphate compound is adhered; and heat treating the fluorescent material particles to which the phosphate compound is adhered at 500° C. to 700° C.
