Luminous glass conversion of oxyhalogen tellurate

Abstract

The invention is an oxyhalogen tellurate upconversion light-emitting, and its characteristic: its components and component contents (mol%) as follows: TeO2 58-80, PbF2 + PbCl2 10-30, BaO + BaF2 0-10, XY (X = Na and K; Y = F and Cl) 0-10, ZnO + ZnBr2 0-10; La2O + Al2O3 0-5, and Yb2O3 + Er2O3 1-4.

Description

technical field [0001] The invention relates to tellurate glass, in particular to an up-conversion luminescent glass of halogen oxytellurate. Background technique [0002] Short-wavelength lasers such as blue-green lasers have very broad application prospects in information processing, data storage, underwater communication, video display, laser printing, laser detection, laser medicine, laser lighting and surface treatment. In data storage, by replacing the red read-write head with blue-green wavelength lasers, the capacity of existing optical discs can be increased by about 4 times; in laser printing equipment, printing speed and resolution can be improved. Among several methods for obtaining blue-green laser output (see prior art Yang Jianhu, Dai Shixun, Jiang Zhonghong, Up-conversion luminescence of rare earth ions and its research progress, Progress in Physics, 2003, No. 3 p.284-298) , the upconversion luminescence using rare earth ions has the following advantages: ...
