- <p><strong><em><span lang="EN-US">A simple low temperature co-precipitation method, which was based on the reactions of zinc nitrate and hexamethylenetetramine (HMT) in aqueous medium at 375 K for 24 h, was proposed for the synthesis of hexagonal ZnO nanoparticles. The ratio of zinc nitrate and HMT was 1:1 M. Structural, morphological, and optical characterization of the as-synthesized nanoparticles was done through X-ray diffraction, field-emission scanning electron microscopy, photoluminescence spectroscopy, and ultraviolet-visible spectroscopy. The novelties of present work was we achieved first time hexagonal structure of ZnO at nanolevel at relatively low temperature (375 K) than reported in the literature and semiconducting band gap for hexagonal ZnO nanoparticles. This research articles, provides an efficient method for synthesis of hexagonal structure of ZnO at nanolevels. Ultra-violet spectra indicated that the as-synthesised hexagonal ZnO has a direct band gap of about 2.78 eV</span></em></strong><strong><em><span lang="EN-US">. </span></em></strong></p> <p><strong><em><span lang="EN-US">Keyword<span>:</span></span><span lang="EN-US"> </span><span lang="EN-US">- </span></em></strong><em><span lang="EN-US">Band gap; Hexagonal ZnO; Co-precipitation Method ;Nano -particles</span></em></p>
