STRUCTURAL ANALYSIS OF CBD γ-MnS THIN FILMS

摘要

This paper presents the preparation of γ -MnS thin films from three different chemical baths having the chemicals manganese acetate, triethylamine, ammonium chloride, hydrazine hydrate and thioacetamide. The preparative parameters were optimized to obtain good quality MnS thin films. The reaction of formation of MnS was discussed in this paper. XRD analysis is employed to confirm the structure and nature of γ-MnS thin films. The calculated crystallite size ranges from 40-54 nm, indicating that the as-prepared MnS films are made up of nanocrystals. EDAX spectra enabled to identify the film as Mn1.2S0.8. SEM pictures showed the hollow spherical morphology of the prepared γ-MnS thin films. FTIR spectra of γ-MnS thin films have also been analyzed and discussed in this paper
