Problems solved by technology

However, there is no literature report on the system glass of phosphorus pentoxide and antimony fluoride
[0008] Most of the existing fluorophosphorus glass systems have complex composition ratios and require various special conditions to obtain excellent glass, and the glass absorption limit is mostly in the short-wave band, and the ability of the glass to absorb pump light is weak, which is not conducive to its use as a rare earth doped luminescence Substrates and other applications in the field of optical technology

Abstract

The invention relates to phosphorus pentoxide and antimonic cluoride system matrix glass and a preparation method thereof. By adopting antimony ions as heavy metal ions, forming capability of fluorophosphate glass is improved, an infrared cut-off of the glass is enabled to shift towards a longer wavelength, optical absorbing range is enlarged, and the phosphorus pentoxide and antimonic cluoride system matrix glass is better in comprehensive performance as compared with a fluorophosphate glass system studied before. The phosphorus pentoxide and antimonic cluoride system matrix glass is high in ultraviolet transmission rate and infrared transmission performance; due to moderate matching of P2O5 and SbF3, the glass is less prone to devitrification, high physical and chemical stabilities are provided, and an excellent medium for compositing new glass systems by doping rare earth ions or other fluorides or oxides in the next is provided.

Description

technical field [0001] The invention belongs to a new fluorophosphorous system glass, in particular to a phosphorus pentoxide and antimony fluoride system matrix glass and a preparation method. Background technique [0002] Fluorophosphorus glass is an optical material that combines the advantages of fluoride glass and phosphate glass. widely. Its low nonlinear refractive index and high stimulated emission cross-section period become the glass for high-power ultrashort pulse tunable laser; its high refractive index, high Abbe number, low dispersion and high special partial dispersion value and Good infrared and ultraviolet optical transparency makes it widely used in optical devices; at the same time, fluorophosphorus glass is used as a rare earth ion doped laser medium, which has a wide fluorescence linewidth and high solubility of rare earth ions. In addition, the low refractive index of fluorophosphorus glass and the compatible chemical and mechanical properties of fluo...
