KARAKTERISASI SIFAT OPTIK DAN MORFOLOGI NANOROD ZnO YANG DIDOPING GALIUM (ZnO;Ga)

Abstract

ZnO nanorods have been successfully grown on the surface of FTO (Fluorine Tin Oxide)by
hydrothermal method at a temperature of 90 ° C for 8 hours. In this study,It will be analyzed the
effect of percentage variation of gallium at 0%, 0.5%, 1%, 1.5%, 2%, 2.5% and 3% to the optical
and morphological properties of the grown ZnO nanorods. The samples were analyzed using
UV-Vis spectroscopy and Field Emission Scanning Microscope (FESEM). The UV- Vis spectra
showed that the strong reflectance observed at the wavelength of 400-800 nm. The 2.5% Ga
doped ZnO was the lowest reflectance compared to other samples. The FESEM images showed
that gallium doped ZnO nanorods grew ontothe surface FTO with hexagonal face shape. It was
also observed that the 2.5% doped Ga sample was the most uniform and formed vertical
orientation array.
