Abstract
Zinc oxide (ZnO) nanostructures with different kind of morphologies were synthesized on glass substrates via the hydrothermal aqueous chemical growth method utilizing c-axis oriented ZnO thin film as seeded catalyst. By preparing ZnO thin film at different molar concentrations between 0.2~1.0 M, oval shaped ZnO nanostructures mixed with ZnO nanowires and rod shaped ZnO nanostructures mixed with ZnO nanowires were produced after immersion process into 0.0002 M zinc nitrate solution for 24 hour. The XRD spectra show synthesized ZnO nanostructures were ZnO hexagonal wurtzite crystalline. The photoluminescence (PL) measurement indicates the luminescences of the samples were depending on the shapes of ZnO nanostructure.
