A simple and general microwave route is developed to synthesize nanostructured ZnO using Zn(acac)2·H2O (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...
The ZnO nanotretapods prepared by a catalyst-free thermal oxidation between zinc vapor and oxygen were studied by X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and photoluminescence spectroscopy (PL). To improve the gas-mixing in the reactor, nitrogen gas was supplied in pulse into the reaction zone. This method could affect the oxygen vacancy...
ZnO nanostructures were grown from a solution of zinc nitrate hexahydrate and hexamethylenetetramine onto different substrates that were pretreated with an RF sputter coated ZnO seed layer. The choice of substrate was observed to have a direct effect on the morphology, orientation and surface coverage of the nanostructured arrays. Substrates that were covered in a 1.2 mum sputter coated ZnO seed layer,...
