Characterization of 2 hrs thermal aged AsAgS films deposited on quartz substrate by thermal evaporation technique was investigated. XRD of the as prepared and 423 K 2 hrs thermal aged AsAgS films show poly crystalline nature with preferred orientation 306 and 624. Elevating temperature decreases both the poly crystalline nature and its optical gap from 2.4 to 2.27 eV due to bonds’ breaking. Other optical constants; refractive index and other dispersion parameters were affected as well.

沉积在石英衬底上的两小时热老化 AsAgS 薄膜的纳米结构和光学特性：新的时间因素

研究了通过热蒸发技术沉积在石英衬底上的 2 小时热老化 AsAgS 膜的表征。所制备的和 423 K 2 小时热老化 AsAgS 薄膜的 XRD 显示具有优选取向 306 和 624 的多晶性质。由于键断裂，升高温度将多晶性质及其光学间隙从 2.4 eV 降低到 2.27 eV。其他光学常数；折射率和其他色散参数也受到影响。
