| Abstract: | Vertically aligned ZnO nanorods were electrodeposited on the ZnO thin films grown by magnetron sputtering. The ZnO thin films were served as a homoepitaxy layer for the growth of ZnO nanorods. The rods were perfectly oriented in a vertical direction and there were no side branches. The ZnO nanorods grown on ZnO thin films have a good crystal quality with a low defect concentration and greatly improve the photoluminescence property of the thin films. The redshift of the peak energy with rising temperature in temperature-dependent photoluminescence spectrum for the UV emission proved its excitonic origin. |
