中文摘要：
采用传统的熔融–淬冷法制备了系列GexTe65Se（35–x）（x=20,22,23,24;摩尔分数,x%）Te基硫系玻璃。利用X射线衍射、差示扫描量热分析、分光光度计、红外光谱仪等设备研究了玻璃的性能。这些玻璃具有良好的热稳定性和红外透过性能。组分为Ge23Te65Se12,Ge24Te65Se11的玻璃的差示扫描量热曲线中没有出现析晶峰,表明玻璃具有良好的抗析晶性能。组分为Ge24Te65Se11的玻璃的转变温度Tg最高,达到了188℃。这些玻璃样品的红外透过范围都很宽,从近红外的1.8μm到远红外的18μm。通过在玻璃的制备工艺中引入蒸馏提纯工艺可以有效减弱杂质吸收峰对玻璃红外透过性能的影响。最后,选用Ge23Te65Se12玻璃作为包层,Ge24Te65Se11玻璃作为纤芯,采用棒管法完成了具有纤芯包层结构的Ge-Te-Se红外光纤的拉制。
英文摘要：
GexTe65Se（35-x （x = 20, 22, 23, 24, in mole fraction, x%） Te-based chalcogenide glasses were prepared by a conventional melt-qluenching method in a silica tube under vacuum. The performance of these glasses was analyzed by X-ray diffraction, differential scanning calorimetry （DSC）, visible/near-infrared （IR） absorption spectroscopy and infrared transmission spectroscopy. These glasses appeared to have excellent thermal stability and transmission properties. There was no crystallization peak on the DSC curve for the two glass compositions, namely, Ge23Te65Se12 and Ge24Te6sSe11, indicating a notably enhanced resistance to crystallization and a maximum value of Tg at 188℃ for the glass composition Ge24Te65Sell. The optical transmission window was from 1.8 μm in the bandgap region to 18 pan in the phonon region. A distillation process that could effectively eliminate the absorption bands in the IR region was used for these glasses. The fabrication （rod-in-tube method） and fiber drawing were both conducted with glass compositions of Ge23Te65Se12 and Ge24Te65Sen as cladding and core, respectively. The Ge-Te-Se infrared optical fiber with core-cladding structure exhibited good fiber drawing properties.
