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