PREPARATION, CHARACTERIZATION AND OPTICAL PROPERTIES OF CDSE THIN FILMS

Abstract

CdSe thin films were deposited by pulsed electrodeposition technique onto stainless steel substrates in galvano statics mode by using an aqueous acidic bath containing CdSO4 and SeO2 in optimized proportion. The growth progress of the film was studied. The deposition parameters such as concentration of electrolyte, time of deposition of film, current density and pH of electrolyte are optimized. The analysis of such deposited filmwas done with electron dispersive spectra (EDS) and X-ray Diffraction (XRD), showed presence of polycrystalline nature of the deposited film.The Scanning Electron Microscope (SEM) gives the surface morphology of the deposited filmsand is observed well adherent and grains are uniformly distributed over the surface of substrate.
