Effect of the ZnO Seed Layer Prepare three different hydrothermal growth techniques for ZnO nanorod (VI).

Abstract

ZnO nanorods (ZnO NRs) were made using physical processes, including dip-coating, evaperation, and hydrothermal. Using X-ray diffraction, the structure of ZnO NRs was investigated (XRD). To examine the absorption spectra, a UV-visible spectrometer was employed. Using (FESEM) , ZnO NRs was investigated (FE-SEM). The produced ZnO NRs have a hexagonal phase structure, according to a (XRD) research. Additionally, the ZnO NRs' average crystallite size ranged from 12.15 nanometers to 48 nanometers ( Scherrer ), respectively. The obtained ZnO nanorod samples have demonstrated nanoparticle-shape of the first prepared seedlayer by dip coating and radial hexagonal-shape of the second prepared seedlayer via hydrothermal technique, according to FE-SEM results. The estimated direct band gaps energies for the ZnO NRs' absorption spectra were 3.21 and 3.48 eV and 382 and 400 nm, respectively.
