RAW MATERIAL MIXTURE FOR NITRIDE-BASED OR OXYNITRIDE-BASED FLUORESCENT MATERIAL AND METHOD FOR PRODUCING NITRIDE-BASED OR OXYNITRIDE-BASED FLUORESCENT MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a nitride-based or oxynitride-based fluorescent material having light-emission intensity higher than heretofore.;SOLUTION: The nitride-based or oxynitride-based fluorescent material having light-emission intensity higher than that of a conventional fluorescent material obtained by a conventional method is obtained by using a raw material mixture for the nitride-based or oxynitride-based fluorescent material, which contains an europium siliconitride powder including trivalent europium. A method for producing the raw material mixture for the fluorescent material includes mechanically mixing the europium-containing siliconitride powder and a host crystal raw material compound.;COPYRIGHT: (C)2010,JPO&INPIT
