Studying the Effect of Annealing on Optical and Structure Properties of Zno Nanostructure Prepared by Laser Induced Plasma
In this paper, Zinc oxide were deposited on a glass substrate at room temperature (RT) and two annealing temperatures 350ÂºC and 500ÂºC using laser induced plasma technique. ZnO nanofilms of 200nm thickness have been deposited on glass substrate. X-RAY diffraction (XRD), atomic force microscopy and UV-visible spectrophotometer were used to analyze the results. XRD forms of ZnO nanostructure display hexagonal structure with three recognized peaks (100), (002), and (101) orientations at 500ÂºC annealing temperature. The optical properties of ZnO nanostructure were determined spectra. The energy gap was 3.1 eV at 300 oC and 3.25eV at 500ÂºC annealing temperature.
