An oxynitride phosphor includes an alpha-sialon as the main component, which is represented by the formula: MxSi12-(m+n)Al(m+n)OnN16-n:Lny (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, A1=D50/DBET@3.0 or the aggregation index A2=D50/Dparticle@3.0; and a production method and usage of the phosphor. |
