520			_aZnO nanorods have grown on glass substrates by Chemical Bath Deposition. Effect of reactants (Zinc Nitrate and HMTA) concentration on growth, morphology and dielectric properties of ZnO nanorods has investigated. Structural properties of ZnO nanorods investigated by X-ray diffraction technique revealed that the intensity of peak corresponding to (002) plane has observed to increase as the concentration of reactant increases from 25 to 100 mM. The average crystallite size estimated by Scherrer’s equation is 10.05, 12.27, 10.21, 9.67 and 10.35 nm for the concentrations of 25, 50, 75, 100 and 125 mM, respectively. Size and shape of the nanorods observed through micrographs obtained from Scanning Electron Microscope showed that morphology of ZnO nanorods exhibit significant dependence concentration of reactants. Impedance analyzer has used to study the dielectric properties of nanorods and results showed high magnitudes of dielectric constant at high frequency due to polarization presenting abnormal behavior of semiconducting materials. The observed characteristics of ZnO nanorods demonstrated that they would be viable in advanced electronic and optoelectronic applications.
