Abstract: Nanorods of ZnO are synthesised using thermal evaporation method. In this method, Zn powder is evaporated at a temperature of 400°C in the presence of oxygen and argon gases. The crystallinity of these ZnO nanorods is studied using XRD. The XRD pattern suggests that these as-grown nanorods are crystalline and diffraction pattern are indexed to a typical wurtzite structure. This agrees well with the reported data (JCPDS card no. 36-1451). It is clear from the transmission electron microscope (TEM) images that the diameter of these nanorods varies from 20 nm to 70 nm and their length is of the order of several hundred nanometers. The UV-Vis spectra show a broad peak at 379 nm, which is a characteristic of ZnO.
