Production of PbS by the method of chemical bath deposition at relatively low solution temperatures

Abstract

As the aim of this study, we produced PbS thin films by the chemical bath deposition method. While producing the films, the solution temperatures were reduced from 20 degrees C down to 0 degrees C. According to XRD patterns, it was observed that all the films had galena-type cubical crystal structures. In addition, it was found that the crystallite sizes increased depending on the increasing solution temperatures. When the morphologies of the film surfaces were examined with the SEM device, it was seen that the film produced at 10 degrees C was pinhole-free. According to the SEM images, it was noticed that the surface roughness of the films obtained at 0, 5, and 10 degrees C was higher than that of the other samples. The film photo showed that all films were deposited onto the glass surface tightly.
