A Detail Investigation on Structural and Optical Properties of ZnO: Sn Prepared by Co-Precipitation Method

ZnO: Sn nanopowders were synthesized by co-precipitation method using Zinc acetate dihydrate and Tin chloride as a precursors. Co-precipitate of ZnO: Sn nanopowders with pure Zinc and different volume fraction of Tin chloride (0.250, 0.050, 0.1 M) and were obtained by calcination process at 500 o C. From the XRD studies revealed that the grain size gradually decrease during increase content of the Sn. The transformation of structural properties of the Sn dopant were confirmed by FESEM. From the EDAX result confirm the presence of ZnO and Sn in the powder.From the FT-IR spectra the chemical bonding and the presence of particles of Sn were confirmed. From the UV-Vis spectra the doped Sn increase band gap than pure Zinc were confirm. From the PL studies blue region of the ZnO: Sn nanopowders were confirm. These results indicate that the crystallinity and structural of ZnO nanopowders are significantly affected by Sn dopant.
