Abstract

Nanostructured Zinc Oxide has been synthesized by employing sol-gel method process using Zinc acetate as the metal precursor and Triethanolamine as a sol stabilizer. The synthesized material has been characterized by XRD, TEM and FTIR. The average particle size of ZnO was 23nm. The XRD analysis of the sample shows formation of nanocrystaline material with Wurtzite ZnO structure. UV visible spectra show maximum absorbance at 360 nm showing ? ? ?* transition of ZnO molecule. The band gap energy is calculated by DRIFTS which shows 3.26 eV.


Keywords
