“…Zinc oxide (ZnO) with a wide direct bandgap of 3.37 eV and a large exciton binding energy of 60 meV, is one of the most extensively studied semiconducting materials for use in various types of applications [ 1 , 2 , 3 ]. One-dimensional ZnO nanostructures have become a subject of interest in the last decade due to their remarkable potential applications in electronics and optoelectronics devices such as photodetectors [ 2 , 4 ], light-emitting diodes [ 5 ] and solar cells [ 6 , 7 , 8 ]. Diverse group morphologies of ZnO nanostructures such as nanorods, nanowires, nanonails, nanotubes, nanocombs, nanosheets, nanobelts and nanoribbons have been synthesized by various physical and chemical fabrication techniques.…”

The formation of high-density zinc oxide (ZnO) nanorods on porous silicon (PS) substrates at growth temperatures of 600–1000 °C by a simple thermal evaporation of zinc (Zn) powder in the presence of oxygen (O2) gas was systematically investigated. The high-density growth of ZnO nanorods with (0002) orientation over a large area was attributed to the rough surface of PS, which provides appropriate planes to promote deposition of Zn or ZnOx seeds as nucleation sites for the subsequent growth of ZnO nanorods. The geometrical morphologies of ZnO nanorods are determined by the ZnOx seed structures, i.e., cluster or layer structures. The flower-like hexagonal-faceted ZnO nanorods grown at 600 °C seem to be generated from the sparsely distributed ZnOx nanoclusters. Vertically aligned hexagonal-faceted ZnO nanorods grown at 800 °C may be inferred from the formation of dense arrays of ZnOx clusters. The formation of disordered ZnO nanorods formed at 1000 °C may due to the formation of a ZnOx seed layer. The growth mechanism involved has been described by a combination of self-catalyzed vapor-liquid-solid (VLS) and vapor-solid (VS) mechanism. The results suggest that for a more precise study on the growth of ZnO nanostructures involving the introduction of seeds, the initial seed structures must be taken into account given their significant effects.

A simple and general microwave route is developed to synthesize nanostructured ZnO using Zn(acac) 2 ·H 2 O (acac = acetylacetonate) as a single source precursor. The reaction time has a great influence on the morphology of the ZnO nanostructures and an interesting spindle-like nanostructure is obtained. The microstructure and morphology of the synthesized materials are investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM) and selected area electron diffraction (SAED). It is found that all of them with hexagonal wurtzite phase are of single crystalline structure in nature. Ultraviolet-visible (UV-vis) absorption spectra of these ZnO nanostructures are investigated and a possible formation mechanism for the spindle-like ZnO nanostructures is also proposed.
