Synthesis and Characterization of Co-doped Zinc Oxide Nanorods Prepared by Ultrasonic Spray Pyrolysis and Hydrothermal Methods
AIP conference proceedings(2017)
Abstract
ZnO nanorods was synthesized by using ultrasonic spray pyrolysis deposition process and grown by hydrothermal method on a glass substrate. The influences of varying Co doping in structural, morphological and optical properties were investigated by X-Ray Diffractometer (XRD), Scanning Electron Microscopy (SEM), and UV-Visible (UV-Vis) spectrometry, respectively. All the nanorods exhibit polycrystalline wurtzite stnicturc with smaller crystalline size on the Co-doped nanorods. The nanorods also show no orientation alignment and random particle size. Interestingly, the nanorods with 3 wt.% Co doped shows high absorbance at UV and visible region indicating that optical properties of the ZnO nanorods have been modified by Co doping.
