| 摘 要： | 采用熔融-淬冷法制备了摩尔组成为(100-x)(0.85GeS2-0.15Ga2S3)-xAgC l(x=0,5,10,15,20)硫卤玻璃,测试了样品的密度、转变温度、析晶温度、可见到中远红外透过光谱、吸收光谱以及折射率参数,根据Z-扫描测试原理用钛宝石飞秒激光器测试了样品的三阶非线性特性.利用经典的Tauc方程计算了样品光学带隙允许的直接跃迁、允许的间接跃迁及Urbach能量.讨论了玻璃的摩尔折射度、金属标准值、光学带隙、Urbach能量对玻璃样品折射率的影响.结果表明:该系统玻璃具有较宽光谱,从可见到中远红外透过区域(0.46~11.50)μm,可作为潜在的多光谱成像材料.随AgC l含量的增加,玻璃的折射率随着摩尔折射度增大而增大,金属标准值、光学带隙与Urbach能量有减小的趋势,而玻璃的三阶非线性性能得到明显提高.
