<P>PROBLEM TO BE SOLVED: To provide a sintered phosphor layer made proof against deterioration caused because the organic solvent binder resin otherwise contained therein is deteriorated by light in a high-power short-wavelength region (blue to ultraviolet region) by removing the organic binder resin contained therein by sintering. <P>SOLUTION: A mixture containing a phosphor powder, an organic solvent binder resin, and an inorganic sintering aid is molded into any desired shape, and the organic binder resin which is the cause of deterioration of the phosphor layer is removed from the shaping by sintering. <P>COPYRIGHT: (C)2004,JPO |
