Abstract

A Tm3+ / Yb3+ codoped oxyfluorotellurate glass with high up-conversion power to strong blue light is prepared by fusion method. It contains TeO2, B2O3, PbF2, WO3, ZnF2, Tm2O3 and Yb2O3 proportionally. Its advantages are high transparency, excellent physical and chemical properties, and strong blue light converting power.

Description

technical field [0001] The present invention relates to a Tm 3+ / Yb 3+ Co-doped oxyfluorine tellurate glass and its preparation method. It is a high-efficiency blue light up-conversion material. Background technique [0002] Blue-green light band laser has a wide range of application value in high-density data storage, submarine communication, large-screen display, detection, especially laser medical treatment and other fields. Especially in optical storage devices, since the amount of information stored in the optical disc is a function of the square of the reciprocal of the laser wavelength of the "read-write head", if a short-wavelength blue laser is used to replace the red-light "read-write head", it can significantly increase the optical capacity of the optical disc. storage density, thereby greatly increasing the capacity of the disc. According to reports, Taro Takamine, a spokesman for Japan's Sony Corporation, said that the company has developed a new optical dis...
