Abstract

Metal oxide nanoparticles have potential applications in a wide range of fields like medicine and environmental science. 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 semiconductors 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.  This work was intended to synthesize Tin oxide (SnO₂) nanoparticles via a one-step hydrothermal method and 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), Ultraviolet Diffusion Reflectance Spectroscopy (UV-DRS) and Photo Luminescence (PL). The dependence of structural and optical properties with temperature was discussed.
