Abstract

Fine layers of barium stannate nanoparticles have been synthesized by sol–gel technique with tin chloride pentahydrate (SnCl4·5H2O) and barium sulphate (BaSO4). Physico-chemical properties of barium stannate, BaxSnO2+y; x:y ≈ 1:1 were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy and UV–Visible spectrophotometry technique. A growth mechanism based on the combination of particle sticking and molecule level heterogeneous growth is proposed. It has been found that the particle size of all the samples was distributed in the range 3.0–6.5 Ǻ while optical absorption spectrum indicates that BaxSnO2+y nanoparticles have a direct band gap of 3.9 eV.
