Abstract
AbstractPure and Pb‐doped MnS thin films are prepared by chemical bath deposition (CBD) method onto glass substrates at 60 °C temperature. The films are characterized by X‐ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X‐ray analysis, and optical absorption spectroscopy. The particle size of the crystalline is determined from the XRD patterns using Scherrer formula and is 47 nm for MnS thin films. The particle size shows a change in the case of the Pb‐doped film. The optical band gap of MnS thin film is found to be 3.1 eV, which decreases on doping with Pb. SEM graphs of doping of Pb in MnS confirmed the formation of spherical superstructure and indicate that the Pb2+ is successfully substituted into the MnS host structure of the Mn2+ site.
