【 摘 要 】

The ZnO nanorods are synthesized by a typical CVD method without any catalyze and substrate. The concentration of nitrogen is changed by a digital gas control system. The influence on the morphology is studied in detail. Under lower amounts of nitrogen the diameter of nanorod is smaller than in the higher one. Meanwhile, the size of the nanorod is bigger in the rich nitrogen amounts. The morphology of the sample is carry out by SEM, and the crystal structure information is giving by XRD. All the measurement told that the nanorods have a great hexagonal wurtzite structure.
