Characterization of ZnO:Sn nanopowders synthesized by co-precipitation method

Abstract

ZnO:Sn nanopowders were synthesized by co-precipitation method using zinc acetate dihydrate and tin (IV) chloride hexahydrate as a precursors. Co-precipitate of ZnO:Sn nanopowders with various Sn additive 0-50 %wt were obtained by calcination process at 500 °C. The corresponding functional groups and chemical bonding of the samples were investigated by Fourier Transform Infrared Spectroscopy (FTIR). The effects of Sn addition on structural and morphological properties of ZnO:Sn nanopowders have been investigated by X-ray diffraction (XRD), Raman Spectroscopy (Raman) and Scanning electron microscopy (SEM). The chemical bonding of Zn-O, Sn-O and Sn-OH in ZnO:Sn nanopowders were observed by FTIR results. The phase formation of this coumpound was observed with increasing Sn content with calcined at 500 °C. These results indicate that the crystallinity and structural of ZnO nanopowders are significantly affected by Sn dopant.
