Abstract

Transparent semiconducting silver sulfide (Ag₂S) thin films were deposited by chemical bath deposition technique on glass substrates. The effect of different deposition temperatures (10, 20, and 30°C) on the structural and optical properties of silver sulfide films was studied. The XRD spectra showed that the structure of the films was monoclinic and polycrystalline, and the predominant growth of crystals was at the plane (022). The intensity of the peaks increases with increasing preparation temperature, becoming narrower and clearer. The best-structured films with the least crystalline defects were that prepared at 30°C. UV-VIS spectroscopic scanning showed that all films had a minimum transmittance and maximum absorbance at the ultraviolet field within the range 300–350 nm. The transmittance decreased and absorbance increased with increasing wavelength and temperature. The energy gap values changed within the range 2.105–2.242 eV, which clearly increased with increasing preparation temperature.

温度对化学沉积法制备的硫化银薄膜的结构和光学特性的影响

通过化学沉积技术在玻璃基底上沉积了透明的半导体硫化银（Ag2S）薄膜。研究了不同沉积温度（10、20 和 30°C）对硫化银薄膜结构和光学特性的影响。XRD 图谱显示，薄膜的结构为单斜多晶结构，晶体主要生长在平面（022）上。峰的强度随着制备温度的升高而增加，变得更窄、更清晰。在 30°C 下制备的薄膜结构最好，晶体缺陷最少。紫外-可见光谱扫描显示，所有薄膜在 300-350 纳米范围内的紫外场都具有最小透射率和最大吸光度。随着波长和温度的增加，透射率降低，吸光度增加。能隙值在 2.105-2.242 eV 范围内变化，随着制备温度的升高，能隙值明显增加。
