Open publisher page 0 citations

Abstract

A single crystallized Co doped ZnO nanorods was synthesized by a hydrothermal method. The results of Transmission electron microscopy (TEM) indicates that the average size of ZnO nanoparticles is 50nm and has a narrow size distribution. Using the ZnO seeds as the nucleus of the Co-ZnO nanorods during their growth, the nanorods could be obtained with a diameter of 40～ 70nm and the length of 0.5μ m. The nanorods grow along 001 direction. Possible roles of ZnO seeds and polymer in the growth of ZnO are also discussed.
