چکیده انگلیسی
Silver doped indium sulphide thin films (In2S3:Ag) were deposited by spray pyrolysis technique on glass substrates at temperature 350â¯Â°C. The films were prepared by varying the Ag:In ratio from 0% to 8%. The effect of silver concentration on structural and optical properties of In2S3:Ag thin films have been studied in detail using X-ray diffraction (XRD) and ultra violet, visible and near infra red (UV-Vis-NIR) transmittance spectroscopy. The X-ray diffraction analysis showed that the prepared layers are polycrystalline and crystallize in a β-In2S3 cubic structure and the size of the crystallites varies between 16 and 20â¯nm. UV-Vis-NIR spectroscopy measurements revealed that the optical transmittance of the films exceeds 90% in the visible and near infrared region and also the direct band gap energy of the fabricated thin film samples increases with doping from 2.63 to 2.97â¯eV. The roughness values evaluated are almost constant for different doping concentration.
