Abstract :
ZnO nanorod was prepared by microwave assisted method. The crystal structure of the nano powders were confirmed by X-Ray diffraction analysis and the mean particle size was estimated by the Scherrer,s formula .The surface morphology of the nano particles were analyzed by using SEM . The absorption spectrum of the material in the UV-Vis range was recorded .The energy band gap of the material was obtained from the absorption wavelength of the UV-Vis spectrum. The short emission wavelength of the material was confirmed by using Photoluminescence studies. The effects of frequency on the dielectric behaviour and ac electrical conductivity have been studied.
