A novel approach using low-cost and simple-equipment was successfully demonstrat ed on the growth of ZnO microrod array films. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) has characterized the microstructure of the samples . The results indicate that ZnO microrod array films are hexagonal, highly orien ted crystalline array films, grown along c-axis of ZnO on (0001) sapphire substr ates. The FWHM is about 1.8° for the (0004) rocking curve of the ZnO films. The photoluminescence spectra of ZnO array films show a strong and narrow peak at 395nm.
