论文摘要
在最近的论文中[执行器。物理。 301（2020）111749] Shkir等。已经研究了CDS薄膜的结构，光学和光电特性，这是欧盟掺杂浓度的函数。作者使用了错误的方程来计算折射率，并且获得的值不正确。因此，基于折射率获得的光学特性，例如介电常数的真实和虚构部分，介电损耗，光学电导率，非线性折射率（N2），线性和三阶非线性光敏感性是错误的。
In a recent paper [Sens. Actuator. A Phys. 301 (2020) 111749] Shkir et al. have studied the structural, optical and photo-electrical properties of the CdS thin films as a function of Eu doping concentration. The authors have used a wrong equation to calculate the refractive index and obtained values are incorrect. Consequently, the optical properties obtained based on the refractive index such as real and imaginary parts of dielectric constant, dielectric loss, optical conductivity, nonlinear refractive index (n2), linear and third-order non-linear optical susceptibility are wrong.
