Hydrothermal Synthesis and Characterization of Tin Oxide (SnO2) Nanoparticles

Metal oxide nanoparticles have potential applications in a wide range of fields. Tin Oxide (SnO2) has been applied as a semiconductor nanomaterial in electronics. Tin oxide is a widely used and intensively studied n-type semiconductor. The research on tin oxide semiconductor has been growing due to the wide range of applications, especially as photo sensors, catalysts and antistatic coating .The electrical conductivity and luminescence properties of SnO2 are mainly decided by the oxygen vacancy present in it. The intention of this study was to synthesize Tin Oxide (SnO2) nanoparticles via one step hydrothermal method and to study the effect of annealing temperature on its properties. As prepared samples were annealed at two different temperatures and the samples were characterized by Powder X-Ray Diffraction (PXRD), Ultra Violet – Diffusion Reflectance Spectroscopy (UV-DRS) and Photo Luminescence (PL). Dependence of Structural and optical properties with temperature was discussed.
