Effects of the substrate temperature on structural and optical properties of the PbS thin films synthesized using pulsed laser deposition are investigated. The main focus of the present study is to optimize various parameters for good quality films. The study reveals the preferred orientation of (200) reflection plane with compressive stress (-0.31211 GPa) at only 200oC substrate temperature. However, the lowest roughness of the film is also observed at 200oC by using atomic force microscope. Only reflectance spectra are used to determine the band gap of these films in weak absorption region.
