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.

Abstract


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.
