Synthesis and characterization of SnS2

Tin disulfide (SnS$_{2})$ nanoparticles were successfully prepared by colloidal chemistry using the hot-injection approach, starting of tin(II) chloride, sulfur and oleylamine. The phase composition and morphology were analyzed by X-ray diffraction, Raman spectroscopy and scanning electron microscopy (SEM). The results show that the synthesis produces nearly-spherical SnS$_{2}$ nanoparticles around 20-50 nm in size, crystallizing in the hexagonal structure. The elemental analysis carried out by EDAX indicated that the obtained nanoparticles are nearly stoichiometric SnS$_{2}$. A representative Raman spectrum reveals a sharp peak at 313 cm$^{-1}$, which characterizes the hexagonal phase of SnS$_{2}$.
