Small lead sulphide films (PbS) are applied to the parts of the glass slide using a chemical bath processor (CBD) at room temperature for 60 minutes. The visual characteristics of the thin films were measured with a spectrophotometer and some solid state structures were determined by comparing the absorption data at a distance of 300-900 nm using software. The software used three types of simulation. SEM micrograph, Band gap (Eg), Absorbance (A), and Raman shift were tested as a function of wavelength and photonenergy. Further analysis has shown that the band gap of PbS films increases as Lead concentration increases.

铅 (Pb) 浓度对 PbS 薄膜结构和光学性能的影响

使用化学浴处理器 (CBD) 在室温下将小的硫化铅薄膜 (PbS) 施加到载玻片的部分上 60 分钟。用分光光度计测量薄膜的视觉特性，并通过使用软件在 300-900 nm 距离处比较吸收数据来确定一些固态结构。该软件使用了三种类型的模拟。SEM 显微照片、带隙 (Eg)、吸光度 (A) 和拉曼位移作为波长和光子能量的函数进行测试。进一步的分析表明，PbS 薄膜的带隙随着铅浓度的增加而增加。
