US20070257232A1 - Light-Emitting Body Dispersed

The present invention provides a light-emitting body in which fine phosphor particles are dispersed in an oxide matrix, with the fine phosphor particles containing at least one selected from oxides and oxysulfides as a parent material. When this light-emitting body is dispersed in a resin, a resin composition having excellent transparency can be obtained.
