Abstract
The arc discharge method was employed to fabricate zinc oxide (ZnO) nanorods with wurtzite structure. The microstructure analysis by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) demonstrated that the ZnO nanorods grew along the [0001] direction. On average, the diameter and length of the nanorods were about 40 nm (some are as thin as 5 nm) and several hundred nanometers, respectively. The photoluminescence (PL) of the nanorods showed an ultraviolet band, a violet band, and a green band. The PL mechanism was discussed with the growth process and Raman spectroscopy.
