Tin disulfide (SnS₂) hexagonal flakes with diameters in the range of 50−150nm are synthesized by using SnCl₂.2H₂O and sodium diethyldithiocabamate as source materials via a solvothermal decomposition route. As-prepared SnS₂ hexagonal nanoflakes are characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), field emission scanning electron microscopy (FESEM), energy dispersive spectroscopy (EDS) and ultraviolet–visible (UV–vis) spectroscopy. The band gap energy of the SnS₂ nanoflakes is measured to be 2.17eV, and the conduction band (CB) and valence band (VB) levels of the SnS₂ nanoflakes are calculated to be −4.34eV and −6.55eV respectively, showing them to be suitable for optional and electronic applications.
