Abstract
An oxynitride phosphor includes an α-sialon as the main component, which is represented by the formula: MSiAlON:Ln(wherein 0.3≦x+y<1.5, 0<y<0.7, 0.3≦m<4.5, 0<n<2.25, and assuming that the atomic valence of the metal M is a and the atomic valence of the lanthanide metal Ln is b, m=ax+by) and in which the aggregation index, A=D/D≦3.0 or the aggregation index A=D/D≦3.0; and a production method and usage of the phosphor.
