Effect on Optical and Antibacterial Activity of SnO<sub>2</sub> and CuO Blended SnO<sub>2</sub> Nanoparticles

Abstract

Nanocrystalline SnO 2 and CuO doped with SnO 2 were prepared by the coprecipitation method and characterized for different physiochemical properties and microbiological activity. The composition and morphological formation were characterized by XRD, HRTEM, Raman, FTIR, and UV-vis spectroscopy. The Powder X-ray analysis reveals that Sn4+ ions have substituted the Cu 2+ ions without changing the monoclinic structure of SnO 2 but the average particle size of the SnO 2 and CuO doped SnO 2 samples from 11 and 5 nm respectively. However, it exhibits an inhibiting strong bacterial growth against tested bacterial strains.
