A STUDY ON OPTICAL PROPERTIES OF SnS NANOPARTICLES

Abstract

Nanoparticles are key components of Nanotechnology, serving as raw materials for the construction of Nanostructures, Nanomaterials, Nanomachines, and Nanodevices. Nanoparticles are defined as "particles with diameters of 100nm or less." Novel features that distinguish nanoparticles from bulk materials often emerge at a crucial length scale of less1than 100 nm. SnS Nanotubules particles were synthesised by the solvothermal method using a precursor materials of tin and sulfur as SnCl2.2H2O and SC (NH2)2. The optical properties of the SnS was characterized by ultraviolet–visible (UV–Vis) analysis and fluorescence study. From the studies, the optical absorption of SnS nanoparticle, has the values of band gap energy (Eg) of 1.77 eV and from PL study the emission is absorbed.
