Abstract

We have synthesized ZnO nanorods by hydrothermal at 95 oC for two hours on different substrates ie glass, ZnO and ITO. Morphologically, the average diameter of ZnO nanorods on glass, ZnO, ITO are 117.6 um, 133 um, 98.4 um, respectively. According to international centre for diffraction data (ICDD) number 01 079 0207, the ZnO nanorods on all substrates possess a polycrystalline wurtzite structure. Optically, ZnO nanorods on a glass substrate have strongest excitonic related ultraviolet (UV) emission. Its predicted, the ZnO seed layer deposited on glass substrate has optimum crystal structure and suppress defects related visible emission.

Keywords: ZnO nanorods, different substrate, polycrystalline wurtzite, UV emission
