Nanocrystalline lead sulphide thin films were deposited on clean glass substrates by chemical bath deposition technique. For the sources of Pb+2 and S-2 ions lead acetate and thiourea were used. To obtain a sample with uniform morphology and pure composition, we investigated and optimized the amounts of experimental variables such as thiourea and lead acetate concentrations, deposition time, pH, and bath temperatures. The size, structure and morphology of Nanocrystalline lead sulphide thin films were systematically characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and UV-VIS spectroscopy techniques.
