<P>PROBLEM TO BE SOLVED: To provide a method for producing a phosphor material, by which a coating layer can efficiently be formed on the surface of phosphor particles, and by which high characteristics and a high yield can be obtained; to provide a phosphor material obtained by the method; and to provide a light emitting device using the same. <P>SOLUTION: A slurry comprising phosphor particles 11, ceramic fine particles 12A, and a liquid is prepared (step S101). Then, the slurry is dried by a vacuum evaporation drying method to remove the liquid and adhere the ceramic fine particles 12A to the surfaces of the phosphor particles 11 (step S102). Subsequently, the slurry is dried, and the phosphor particles 11 adhered to the ceramic fine particles 12A are thermally treated in an inert gas atmosphere (step S103). <P>COPYRIGHT: (C)2013,JPO&INPIT |
