一种含铅硒化物玻璃及其制备方法技术

本发明专利技术公开了一种含铅硒化物玻璃及其制备方法，由ＧｅＳｅ↓［２］，Ａｓ↓［２］Ｓｅ↓［３］，和ＰｂＳｅ组成，其中：ＧｅＳｅ↓［２］的摩尔含量为０～１００％，Ａｓ↓［２］Ｓｅ↓［３］的摩尔含量为０～１００％，ＰｂＳｅ的摩尔含量为０～５０％。本发明专利技术的含铅硒化物玻璃，较之于传统的硫化物玻璃，硒化物玻璃具有更大的质量和更强的共价性，因而具有更长的红外截止波长。砷的引入显著改善了玻璃的热稳定性，适当调整玻璃组成，可以得到高热稳定性较高的玻璃，甚至ＤＳＣ测试表现为无析晶峰出现。本发明专利技术的含铅硒化物玻璃，成玻性能好，加工简单，在红外、光电子、半导体材料等在许多方面具有重要的实际应用。

Lead selenide glass and preparation method thereof

The invention discloses a lead selenide glass and its preparation method, by GeSe: 2, As: 2 Se: 3, and PbSe, among them: GeSe: 2, molar content is 0 ~ 100%, the lower 2 molar content of As Se: 3 the 0 to 100%, the mole fraction of PbSe is 0 ~ 50%. The invention of the lead selenide sulfide glass glass, compared with the traditional, covalent selenide glass has more quality and stronger, so it has a longer wavelength infrared cut-off. The introduction of arsenic significantly improved the thermal stability of glass. By adjusting the composition of glass properly, the glass with high thermal stability could be obtained. Even the DSC test showed an amorphous peak. The lead selenide glass of the invention has good glass forming property and simple processing, and has important practical application in many aspects, such as infrared, photoelectron, semiconductor material, etc..
