Abstract :
As a promising and captivating member of the sulphide family, tin monosulphide (SnS) with its excellent versatility, having fascinating applications with favorable direct and indirect bandgaps, enhanced absorption coefficient (105 cm-1), etc., has ignited distinctive interest in the research community. Recently, the material has gained incredible attention as solar absorber, near-infrared detector, photocatalysts, in holographic recording, and many more. SnS nanostructures were prepared by a facile and robust hydrothermal method using tin chloride dihydrate and sodium sulphide as source materials. The reaction was carried out at optimum 200 °C for varying reaction times of 6, 12, 18 and 24 h. The as-synthesized nanostructures were characterized by powder X-ray diffraction (XRD), High resolution transmission microscopy (HR-TEM), Selected area electron diffraction (SAED), UV-visible absorption spectroscopy (UV) and Photoluminescence spectroscopy (PL) and dielectric analysis. The XRD and SAED patterns expose the single crystalline nature of the SnS nanostructures. The average particle size calculated by Scherrer equation was found to vary from 15-35 nm for the SnS samples. The effect of the reaction time on the properties of the synthesized nanostructures have been critically evaluated. The optical properties studied by UV and PL advocate that the SnS nanostructures can be pertinent entrants for energy applications.
