Full-color light-emitting material and preparation method thereof

Abstract

A full-color light-emitting material and preparation method thereof are provided. A light-emitting material is following general formula compound (Y1-x-y-zAxByCz)2GeO5, wherein 0<x≦0.05, 0<y≦0.15, 0<z≦0.15, x:y:z=1:1˜10:1˜10, A is one of Tm and Ce, B is one of Tb, Ho, Er and Dy, C is one of Eu, Pr and Sm. Preparation method is: grinding the raw material uniformly, then sintering the material at 1300˜1500 ° C. for 6˜24 h, cooling down the material to room temperature then getting the product. A full-color light-emitting material which can emit red-green-blue full-color light directly and be adapted for light-emitting device excited in ultraviolet zone without other doped material is provided. And a preparation method having simple process, stable product quality for full-color light-emitting materials is provided.
