【 摘 要 】

Here, we report the seed/catalyst-free growth of 2D and 3D ZnO nanostructures on a glass substrate by thermal evaporation of Zn powder in the presence of O2 gas. These nanostructures were grown on (75 ± 5 nm) ZnO seed layers, which were deposited on glass substrates by radio frequency magnetron sputtering. Prior to synthesized ZnO nanostructures, the sputtered ZnO seeds were annealed using the continuous waveCO2 laser at 450 ℃ in air for 15 min.The effects of carrier gas flow rate on the morphological, structural, and optical properties were systematically studied using field emission scanning electron microscopy, X-ray diffraction and UV-Vis spectroscopy.
