Abstract

A ceramic composite material for light conversion, which is a solidified body comprising two or more matrix phases with respective components being two or more oxides selected from the group consisting of metal oxides and complex oxides each produced from two or more metal oxides, wherein at least one of the matrix phases is a phosphor phase containing an activated oxide. The solidified body is preferably obtained by the unidirectional solidification method. The ceramic composite material for light conversion is excellent in brightness, light-mixing property, heat resistance and ultraviolet light resistance.
