Title:
PROCESS FOR PRODUCING PHOSPHOR, AND PHOSPHOR
Document Type and Number:
WIPO Patent Application WO/2007/023677
Kind Code:
A1
Abstract:
A process for producing a phosphor that attains high purity, excelling in monodispersion and that is improved in luminescent characteristics; and a phosphor produced by the process. There is provided a process for producing a phosphor, characterized by including the steps of preparing a precursor of the phosphor from an aqueous solution containing at least two types of element ions for constituting the phosphor; preventing any aggregation attributed to by-products generated in the phosphor precursor preparing step; removing the by-products generated in the precursor preparing step; and firing the precursor dispersion resulting from the removal of by-products.
