Zinc oxide (ZnO) microrods were fabricated on graphene/SiO(2)/Si substrate by a simple hydrothermal route. The obtained products were characterized using X-ray powder diffraction, scanning electron microscopy, energy dispersive X-ray spectrometry, photoluminescence and UV-visible spectrometry. Microrods exhibits hexagonal wurzite structure. Some ZnO clusters and twinned ZnO structures were foun...

single crystal zno microrods are deposited on the surface of zn plate through corrosion of zn plate by h2o2, which is a green neutral reagent and easy to transform to h2o and o2. the structure and morphology of the obtained zno microrods were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem), transmission electron microscopy (tem) and electron diffraction. a thermodyn...

Tubular ZnO microstructural arrays were fabricated by a hydrothermal decomposition method. The dependence of the morphologies on the growth time and temperature was investigated in detail. An experiment was carried out to determine the mechanism of tubular ZnO formation. Our results showed that ZnO microtubes originated from an ageing process from ZnO microrods at a lower temperature (compared ...

By sputtering a layer of 40 nm Ag film on ZnO microrods prepared by the aqueous solution method, we observed photoluminescence enhancement from ZnO microrods coated with Ag nanoparticles, comparing with pure ZnO microrods. The ratio of the enhancement, in particular, reaches 6.6 at 396 nm. The enhancement mechanism is attributed to the special distribution of the silver nanoparticle film, which...

ZnSO(3) microrods with uniform size and shape can be prepared under microwave irradiation at much higher speed than a conventional heating bath, usually in minutes. The annealing of ZnSO(3) microrods produced porous ZnO microrods with pore size between 50-200 nm.

In this work, several nano/microscale structures of ZnO including nanospindles, microbundles, microrods, and nanoflowers have been prepared via a facile template and surfactant-free hydrothermal method mediated with ammonium molybdate. It is found that the morphology of ZnO could be readily tailored by simple variation of the concentration of ammonium molybdate. The effects of the concentration...

In this work, we have modified the experimental setup for a vapor-solid (VS) process to synthesize Zinc oxide (ZnO) microtubes (MTs) with lengths up to 3 mm during a 90-min growth period. The critical idea behind this modification is to control the distribution of Zn vapor along the Si substrates. The morphology evolution of ZnO structures with the increasing reaction time was particularly expl...
