Abstract

ZnO nanorods have been deposited on ITO glass by electrodeposition method. The optimization of two process parameters (precursor concentration and current) has been studied in order to control the orientation, morphology, and optical property of the ZnO nanorods. The structural and optical properties of ZnO nanorods were systematically investigated by using field-emission scanning electron microscopy, X-ray diffractometer, and photoluminescence. Commonly, the results show that ZnO nanorods with a hexagonal form and wurtzite crystal structure have a c-axis orientation and higher intensity for the ZnO (002) diffraction peaks. Both high precursor concentration and high electrodeposition current cause the increase in nanorods diameter and coverage ratio. ZnO nanorods show a strong UV (3.28 eV) and a weak visible (1.9 ~ 2.4 eV) bands.
