Abstract: In this research, the structural and surface properties of lead oxide thin films (PbO) has been studied. They were prepared by the chemical Spray Pyrolysis method on glass substrates at (450C). the structural properties has been studied using X-ray diffraction (XRD) analysis and the surface properties of the thin film where investigated using atomic force microscopy AFM analysis before and after the subjection of the thin film to cold plasma at different times (5, 10, 15, 20, 25) min. dielectric barrier discharge system were used to generate the cold plasma. The results of (XRD) tests showed that all the prepared films were of a polycrystalline and the thickness of the thin film is slightly decreases when subjected to cold plasma and the average of crystal size rates increasing too. The pictures of atomic force microscope (AFM) showed the values of the average of the surface roughness and the square root (RMS) increases as time of treatment increase
