Abstract

Abstract: Zinc oxide(ZnO) nanorods were successfully synthesized by a simple approach via a direct precipitation method in the presence of PEG-400(polyethylene glycol 400) at room temperature. The characterizations of ZnO nanorods were carried out by XRD, TEM, SAED and HRTEM. The results show that the as-prepared ZnO crystals are one-dimensional nanorsds which are single crystals with a hexagonal wurtzite structure. The ZnO nanorods are uniform with 20—40 nm diameter and lengths ranging from 300 to 800 nm. The (0001) face is the growth direction of the ZnO nanorods. The possible mechanism of the growth of ZnO crystal and the form of ZnO nanorods along with the important effect of PEG-400 on the fabrication of ZnO nanorods were discussed.

Key words: ZnO nanorods, Crystal growth, Direct precipitation, Room temperature
