We have studied the physical properties of CdS thin films obtained by high-frequency magnetron sputtering. We have determined the optical constants and the bandgap width for the studied fi lms (Е_g = 2.39 eV). The spectral dependences of the refractive index, the absorption coefficient, and the extinction coefficient were obtained from the transmission spectra at room temperature. The optical parameters of the films were determined using a singleoscillator model, and also the Cauchy and Sellmeier equations.

CdS薄膜的光学性质

我们已经研究了通过高频磁控溅射获得的CdS薄膜的物理性能。我们已经确定了所研究薄膜的光学常数和带隙宽度（_g = 2.39 eV）。从室温下的透射光谱获得折射率，吸收系数和消光系数的光谱依赖性。膜的光学参数使用单振荡器模型，柯西方程和塞迈尔方程确定。
