Synthesis of SnS₂ nanocrystals via a solvothermal process

Nanoparticles of tin disulfide have been successfully prepared by the solvent-thermal synthesis method using different precursors. The X-ray powder diffraction patterns showed that the products were hexagonal SnS₂ phase and transmission electron microscope images displayed that the samples were laminar particles with the average size of about 150nm. The Raman spectra showed a sharp peak at 311 cm^-1, which is characteristic of SnS₂. The IR spectra determined the absence of tin oxides. In addition, the possible routes of the reactions were discussed.
