Fabrication and optical property of ZnO nanorod array by hydrothermal method

We synthesize a large area of ZnO nanorod array by using the RF magnetron sputtering and low-temperature hydrothermal method. The sample morphology, crystal structure and optical properties are characterized and analyzed by means of the SEM, XRD and fluorescence spectrophotometer. The results show that ZnO nanorod array has the advantages of large aspect ratio, ordered orientation, uniform and compact at a lower OH−/Zn2+ concentration. The XRD...
