Morphologies of ZnO nanorods

ZnO nanorods with different morphologies were fabricated through a simple r eaction method. They were characterized by means of powder x-ray diffractio n (XRD), field emission scanning electron microscopy (FE-SEM) and energy-di spersive x-ray (EDX) spectroscopy. FE-SEM images have shown that the shapes of the ZnO nanorods included straight nanorods, spear-like nanorods with s awtooth-shaped surfaces and lotus root-like nanorods. XRD and EDX indicated that all the nanorods are composed of hexagonal ZnO.
