An object of this invention is to provide the light emission nano microcrystal glass used for a white light LED light source, and its manufacturing method. The glass is non-porous and dense SiO 2 glass in which luminescent nanocrystallites are dispersed, and the chemical formula of the luminescent nanocrystallites is Y x Gd 3-x Al 5 O 12 : Ce (0 ≦ x ≦ 3). It is. The glass has good stability and uniform light emission. In the production method, a compound raw material is dissolved in a solvent to prepare a mixed solution, and the SiO 2 nanoporous glass is immersed in the mixed solution, taken out and dried, and then the temperature is gradually raised to 1100 to 1300 ° C. And baking for 1 to 5 hours to obtain a product. The method is simple in manufacturing process, convenient in operation, and low in cost. |
