Synthesis of zno nanoparticles using carboxymethyl cellulose hydrogel

Abstract

A new approach has been proposed to synthesis pure ZnO nanoparticles from zinc nitrate hexa-hydrate precursor and sodium carboxymethyl cellulose capping1 agent. The resulting nanoparticles were characterized by X-ray Diffraction (XRD), Fourier Transform Infra-red (FTIR) spectroscopy, photoluminescence spectroscopy and Field Emission Scanning Electron Microscopy (FESEM). The XRD results showed that particle size is in the range of few nanometers with hexagonal wurtzite structure. Photoluminescence and FESEM results suggested that the adopted method can be successfully utilized for the preparation of size controlled nanocrystalline ZnO powder.
