Glass with mid-infrared luminescent property, and preparation method and application thereof

Abstract

The present invention provides glass with a mid-infrared luminescent property. The glass is composed of a binary system of Bi2O3 and GeO2, wherein the purity of Bi2O3 and GeO2 is greater than 99.9%, and the mole percent of Bi2O3 is 1-40%. A preparation method includes: mixing Bi2O3 and GeO2 sufficiently, and compressing into blocks, wherein the mole percent of Bi2O3 is 1-40%. The glass is prepared by a melt quenching method. The glass with the mid-infrared luminescent property includes Bi ions, can produce a mid-infrared emission band of ultra-wideband, is stable in physical and chemical properties, easy in material processing, can also be drawn into optical fibers as needed, has good compatibility with other optical system, is simple in excitation conditions, is suitable for laser diode pumping, and can make good use of maturely-developed diode laser as a pumping source, resulting in a compact, high-efficiency and low-cost commercial laser.

AI Technical Summary

Problems solved by technology

These provide strong support for the application of Bi-doped materials in the mid-infrared, but there are also some shortcomings. For example, the above phenomena are mostly observed at low temperatures, and the Bi 5 (AlCl 4 ) 3 Although the above-mentioned materials have mid-infrared luminescence at room temperature, because the preparation temperature of the materials is very low (less than 350°C), the stability and processing performance are relatively poor, so the practicability of the above materials is still relatively lacking.
