Hot Injection Synthesis of Orthorhombic SnS Nanoparticles from Bis(O-n-Propyldithiocarbonato)Diphenyltin(IV)

Abstract

The bis (O-n-propyldithiocarbonato) diphenyl of tin (IV) [Ph2Sn (S2COnPr)2] was synthesized as a precursor for the preparation of SnS nanoparticles. The complex was characterized by X-ray single crystal diffraction, thermogravimetric analyses (TGA), nuclear magnetic resonance (NMR) and IR spectroscopy. Hot injection method was used to synthesize the SnS nanoparticles under nitrogen atmosphere at 260 °C. The SnS nanoparticles formed were studied by powder X-ray diffraction, Raman spectroscopy and transmission electron microscopy (TEM). The phase was found to be polycrystalline, orthorhombic SnS with a strong (111) preferred orientation. The band gap of SnS nanoparticles is 1.28eV.
