%X High-density bat-like ZnO micro- and nanorods were prepared on Si(111) substrates by a thermal evaporation method using Zn powders and zinc acetate dihydrate (ZA) as the source materials. X-ray diffraction, field emission scanning electron microscope, transmission electron microscope, Raman scattering and photoluminescence were used to characterize the structural and optical properties of the obtained samples. The results indicate that the individual rod has four knots with different diameters, the rods are a high-quality single crystal with a few defects. The growth mechanism of the structures proposed reveals that oxygen partial pressures play an important role in the growth process. The shape of ZnO nanostructures can be controlled by adjusting oxygen flux.
