Abstract

The invention belongs to the field of a luminescent material and discloses high-silica blue luminescent glass and a preparation method thereof. The high-silica blue luminescent glass comprises a high-silica nano micropore glass substrate and Re[1-x]TmxVO4 nano luminescent minicrystals which are uniformly distributed in the micropores of the high-silica nano micropore glass substrate, wherein Re is at least one of Y, La and Gd, and x ranges from 1*10<-4> to 0.05. According to the invention, the high-silica nano micropore glass is used as a luminescent ion substrate, and the Re[1-x]TmxVO4 nano luminescent minicrystals are distributed in the micropores of the luminescent ion substrate; and the high-silica nano micropore glass substrate has good ultraviolet light permeable property, which is extremely beneficial to absorption of luminescent particles on excitation wavelengths, thereby improving the luminescence efficiency.

Description

technical field [0001] The invention relates to the field of photoelectric materials, in particular to a high-silica blue luminescent glass. The invention also relates to a preparation method of the high-silica blue luminescent glass. Background technique [0002] With the continuous application of rare earth ion-doped luminescent materials in the fields of lighting, display, laser and light amplification, and information, it is found that rare earth ion-doped nano-luminescent particles can produce more excellent luminescent properties in composite materials, but traditional It is difficult to prepare nano-sized luminescent particles by the solid-state sintering method. Although some new preparation methods at present, such as hydrothermal synthesis method, sol-gel method, etc., can obtain luminescent particles with better dispersion. However, with the development of high-brightness lighting equipment, high-power laser and display technology, the chemical stability, mechan...
