- Abstract
A Ce-doped ZnO nanomaterial was prepared by a simple method of sol-gel and chemical vapor deposition. The structure, morphology, band structure and luminescence properties of the ZnO nanomaterials were analyzed. The results showed that the nanomaterial was similar to a screwdriver, and consisted of a hexagonal micron substrate and a nanorod top. It had a good single crystal structure; its preparation process conformed to the VLS growth mechanism, and the vapor concentrations of Zn and Ce had a very large influence on the growth rate of each crystal face; Compared with ZnO nanomaterials, the Zn 2p3/2 peak in the nanomaterials shifted to a lower energy level, while the 01s peak shifted to a higher energy level. The doping of Ce affected the electronic structure and band gap structure of ZnO; its UV emission peak was reduced and accompanied by red shift, and the intensity of green light emission was improved. The nanomaterial prepared has a good application prospect in assembling nanodevices.
