In this study, PbS thin films were produced at a low temperature such as 15Co using the chemical bath deposition (CBD) method.0.0085 M Pb (NO3)2 and 0.1460 M NaOH were dissolved in 100ml deionized water. 0.510 M thiourea which would be added to the solution was divided into 10 portions and added at zero, two, four, six and eight-minute intervals. Structural analysis of the obtained samples was carried out from XRD patterns which showed a significant increase in the peak intensity of the films obtained by adding thiourea at intervals of four and six minutes. The surface morphologies of the films were analyzed using a scanning electron microscope. According to the SEM images, when thiourea was added to the solution at intervals of four minutes, no cracks and holes were formed on the surfaces of the films obtained.
