Abstract

This study addresses the producing of bi structure zinc oxide (ZnO) via chemical electrodeposition on a conductive coated glass. The current density was fixed at 2mA.cm-2 with different reaction time (deposit time). The produced ZnO shows a polycrystalline nature with prefer orientation towards the (a - axis). The reaction time shows no effect on the crystalline size and the microstrain, which proof the repeatability in the microstructural properties. The scanning electron microscopy (SEM) images show the presence of bi structures, the bottom is a submicron size plates, after that urchinslike structure of ZnO were growth on the edge of the plates. More reaction time produced higher density of the urchins. The ZnO exhibit prominent emission at the UV band (3.27 eV) and no visible emissions were found. Blue (2.83 eV) and red luminescence bands (1.63 eV) were observed which was attributed to zinc interstitial to oxygen interstitial defect levels.
