Abstract

Abstract : Binary thin disulfide (SnS2 ) and ternary Sn1-x Fex S2 (X = Fe (2.5%, 5% and 10%) which has huge potentials in the visible-light rang due to its bandgap 2.2-2.6 eV. Herein, SnS2 and Sn1-x Fex S2 powders have been synthesize by a fruitful hydrothermal method. The structure, morphology, elemental composition and optical properties of the obtained product were characterized by using X-ray diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), Electron Dispersive Spectroscopy (EDS) and UV-Vis spectroscopy. It was found that the Fe could be effectively incorporated in the obtained Sn1-x Fex S2 compounds. According to XRD analysis, increased concentration of Fe in the Sn1-x Fex S2 compounds results in a gradual degradation of the crystallinity. The optical bandgap was found to be 1.52 eV, 2.22 eV, 2.38 eV and 2.48 eV, for the SnS, SnS2, Fe 5% and Fe 10% respectively. Mott–Schottky measurements performed for SnS2 confirm the n-type character of SnS2 samples.
