Abstract: Zinc oxide nanorods were synthesized from zinc nitrate and ammonia solution by precipitation method assisted by microwave irradiation. The molarity of the bath solution was varied as 0.05M and 0.075M. The pH of the bath solution was varied as 7.5 and 8.0 for both the molarities and all samples were annealed at 250ºC. The nanorods were obtained from 0.075M zinc nitrate solution at pH 7.5. The structural and optical properties of the nanorods were characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), and UV-Vis spectroscopy. The thermal characteristics was carried out by Thermo gravimetric and Differential thermal analyzer (TG-DTA) .The obtained nanorods shows length of 250-400 nm and diameter in the range of 45-60 nm. XRD pattern of ZnO nanorods shows hexagonal wurtzite structure with preferred (101) growth direction. The ZnO nanorods have UV absorption at 367.14 nm and the corresponding energy band gap is 3.37eV.
