<P>PROBLEM TO BE SOLVED: To provide a phosphor having an emission color finely adjusted without impairment to its good characteristics and to provide a white semiconductor emitter. <P>SOLUTION: The phosphor is characterized in that fine particles of a compound of erbium (Er) as a rare earth element are adhered to the phosphor. The adhesion of the erbium (Er) compound makes the fine adjustment of a fluorescent color without impairment to the fluorescence intensity, temperature characteristics, etc., of the phosphor. A white semiconductor emitter using the phosphor enables the fine adjustment of the chromaticity of emission color. <P>COPYRIGHT: (C)2010,JPO&INPIT |
