ABSTRACT. The IV–VI semiconductor nanoparticle tin sulphide (SnS), has sparked rigorous interest in the scientific commune because of the array of promising applications it offers such as in photovoltaics, near-infrared detectors and biomedical applications. In the present work, phase pure SnS nanoparticles were effectively synthesized by a green hydrothermal technique using the precursors tin chloride pentahydrate and thiourea. The as-prepared nanoparticles were subjected to various characterizations in order to analyze their optical, structural and transport properties. The Powder X-ray Diffraction (XRD) measurements revealed the purity and crystalline nature of the SnS nanoparticles. The average crystallite size of 10.65 nm, calculated by the Scherrer’s formula was in good agreement with the observations from the Transmission Electron Microscope (TEM)   micrographs.  The transport properties of the synthesized nanoparticles were studied using dielectric analysis. Further, the UV-visible spectroscopy (Uv-vis) and Photoluminescence spectroscopy (PL) results advocate that the primed SnS nanoparticles will be an appropriate applicant for photovoltaic and other light emitting applications.
