Abstract :In the current study, thin films of PbS were fabricated at 35 ᵒC bath temperature via chemical bath deposition insert ignore into journalissuearticles values(CBD); method. During the experiment, 0.1460 M NaOH and 0.0085 M Pb insert ignore into journalissuearticles values(NO 3 ); 2 were dissolved in 100 ml of deionized water and 0.510 M thiourea was inserted. Thiourea, which is used as the ligand source, was inserted to the solution at zero, one point five, three, six and nine minutes intervals, in 10 parts, unlike conventional production methods. When the first sample was produced, thiourea was inserted to the solution at one time and compared with other samples. XRD patterns were used in determining the structural features of the produced films. XRD patterns show that peak density increased significantly when thiourea was inserted at intervals of three, six and nine minutes. A scanning electron microscope insert ignore into journalissuearticles values(SEM); was utilized in analyzing the morphological properties of the films. When SEM images were examined, it was observed that when thiourea was inserted at different time intervals, there were no pinholes.
