摘要：
A novel approach using low-cost and simple-equipment was successfully demonstrated 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 oriented crystalline array films, grown along c-axis of ZnO on (0001) sapphire substrates. The FWHM is about 1.8 degrees for the (0004) rocking curve of the ZnO films. The photoluminescence spectra of ZnO array films show a strong and narrow peak at 395nm.
