摘要
Tin oxide (SnO2) nanoparticles have been synthesized by microwave assisted chemical route method. The as-prepared sample was annealed at 550 degrees C for 1 h for the formation of SnO2 phase. The crystal structure, morphology, optical band gap of SnO2 nanoparticles were investigated by X-ray diffraction (XRD), scanning electron microscopy, transmission electron microscopy, UV-visible spectroscopy, Fourier transform infra-red spectroscopy. XRD result shows that the annealed SnO2 samples exhibited tetragonal crystalline structure with crystallite size ranging from 13 to 25 nm. The optical band gap value of SnO2 nano particles was calculated to be 3.78 eV. The impedance properties of SnO2 nanoparticles were analysed for different temperatures varying between 110 and 150 degrees C and the dielectric properties and ac conductivity are discussed.
