Abstract:
A method for producing a fluorescent material can be provided. The method includes preparing fluorescent material particles that contain a fluoride having a composition including Mn, at least one selected from the group consisting of alkali metal elements and NH4+, and at least one selected from the group consisting of Group 4 elements and Group 14 elements; causing at least one cation selected from rare-earth elements and a phosphate ion to come into contact with each other in a liquid medium containing the fluorescent material particles to obtain rare-earth phosphate-adhered fluorescent material particles including the fluorescent material particles to which the rare-earth phosphate is adhered; and separating the rare-earth phosphate-adhered fluorescent material particles from the liquid medium.
