Shape selective hydrothermal synthesis of tin sulfide nanoflowers based on nanosheets in the presence of thioglycolic acid

Different morphologies of nanostructured tin sulfide (SnS) including nanoparticles, nanosheets and nanoflowers have been prepared via a simple hydrothermal reaction between SnCl2 center dot 2H(2)O and thioglycolic acid (TGA) at relatively low temperature. Products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), ultraviolet-visible (UV-vis) spectroscopy, photoluminescence spectroscopy (PL), and Fourier transform infrared (FT-IR) spectra. The effect of reactant concentration, mole ratio of TGA to the Sn2+, temperature and reaction time on the morphology, particle sizes and phase of nanocrystalline SnS products has been investigated.
