摘　　要：采用传统的熔融-淬冷法制备了一系列的（Ge15Ga10Te75）100-x（Ag）x硫系玻璃样品.通过X射线衍射、差式扫描量热法、傅里叶红外光谱仪等测试了玻璃样品的热学及光学性能.结果表明该玻璃具有良好的非晶态特性和热稳定性,玻璃开始析晶温度和玻璃转变温度的差值都超过了100℃.随着Ag含量的增加,玻璃的吸收截止边产生了红移.通过提纯,Ge-Ga-Te-Ag玻璃在1.8-20μm有着较宽且平坦的红外光学窗口.Ge-Ga-Te-Ag玻璃组分的优良性质使其在红外领域具有广阔的应用前景.A traditional melt-quenching method was adopted to prepare a series of（Ge15Ga10Te75）100-x（Ag）x chalcogenide glass samples.The thermal and optical parameters were measured by X-ray diffraction,differential scanning calorimetry and Fourier transform infrared spectroscopy,etc.The results show that these glasses have well amorphous nature and good thermal stability.The differences between the glass onset crystallization temperature and the glass transition temperature are all beyond100℃.With the addition of silver,the absorption cut-off edge has a red shift.The Ge-Ga-Te-Ag glasses have wide and flat infrared optical windows between 1.8 and 20 μm after a purification method.Therefore,all these properties indicate that Ge-Ga-Te-Ag glasses are potential candidate for far infrared applications.
