摘要：

Three types of hexagonal wurtzite ZnO nanostructures namely nanorods, nanodisks and nanoflowers were prepared in three different pH value solutions. The results indicated that the concentration of H+ ions in the solution would greatly affect the growth behaviors of ZnO crystal. In addition to a broad ultraviolet emission found on the photoluminescence spectra, two weaker peaks corresponding to the blue emission of ZnO were observed at 2.75 and 2.68eV, which probably originate from the electron transition from the shallow donor level of interstitial Zn to the valence band of ZnO.
