Abstract

The invention discloses Y2O3-Ta2O5-B2O3 fluorescent glass and a preparation method thereof.The preparation method comprises the steps that Ta2O5 and Y2O3 are mixed according to the chemical proportion and then ground, and mixture powder is obtained; the preparation method comprises the following steps: adding B2O3 into the mixture powder according to a chemical ratio, sintering, cooling to room temperature through a furnace, soaking the obtained material in deionized water to remove excessive B2O3, drying, and stripping a glass sample to obtain the Y2O3-Ta2O5-B2O3 fluorescent glass. Compared with a traditional glass preparation process adopting a melting and quenching method, the glass material can be prepared by adopting a molten salt method and furnace cooling, quenching is not needed, and the prepared material presents 300-700 nm wide-spectrum fluorescence emission under excitation of 251 nm ultraviolet light and has application characteristics of fluorescent glass; meanwhile, the preparation method is simple and safe, and a new idea for preparing the glass is provided.
