摘　　要：研究了3种杂质消除的预处理方法对硫系玻璃Ge28Se60Sb12红外透过性能的影响.结果发现,石英安瓿瓶经过高温脱羟处理,硫系玻璃中由外源羟基引起的6.3,7.9和12.8μm3处的红外特征吸收降低;玻璃原料中引入除氧剂铝,除[Se-H]键外硫系玻璃中的杂质吸收峰处透过率都得到明显提升,尤其是12.8μm;采用原料整体加热的纯化工艺处理,4.5和4.9μm处[Se-H]键吸收峰的透过率得到提升;将3种杂质消除方法结合在一起,能够有效消除0.9~15μm波段内的杂质吸收峰,获得光学透过性能优异的硫系玻璃.IR optical properties of Ge_(28)Se_(60)Sb_(12) chalcogenide glass pretreated by three different impurities eliminating technologies were studied in this article. Results showed that hydroxyl content of quartz ampoule by high temperature pretreatment was reduced,which caused 6. 3,7. 9 and 12. 8 μm impurity absorption bands in Ge_(28)Se_(60)Sb_(12) chalcogenide glass significantly reduced,the doping Al into the raw material can effectively eliminate [Ge—O]absorbance in chalcogenide glass,while the overall heating of the purification process can significantly improve the transmittance around 4. 5and 4. 9 μm,which was arouse by [Se—H] impurity. The results show the effective combinations of three eliminating impurities ways can access to high quality,and no absorption loss chalcogenide glass.
