Arrays of zinc oxide (ZnO) micro/nano pillars have been synthesized on indium-tin-oxide (ITO) substrates by a solution route under an external electric current. They were pillar-like morphologies and grew along the c-axis. Some comparative experiments showed that applying the external electric current effectively improved the alignment of the product in a short time. It was indicated that the micro/nano pillars can be obtained in a short time under an external electric current.

In previous work, ZnO nanorods and nanoflowers were synthesized on indium-tin-oxide (ITO) substrates by hydrothermal growth at low temperature ,using the different concentrations of equimolar (1:1) zinc nitrate Zn (NO3)26H2O and methenamine (C6H12N4) mixed as precursors solution, and adding ammonia solution to control the pH levels. In this paper, for comparison, the same experiment without ammonia solution was also discussed. SEM, XRD were utilized to characterize morphologies and crystal structures of ZnO. It was indicated that the pH of precursor solution leads to the significantly changes in the nanostructured ZnO. Besides, a hierarchical structure of some of the micro/nanotubes was obtained .The possible growth mechanism is discussed in this work.

Chemical Solution Route

The monodispersed zinc oxide nanowires with lateral dimensions as thin as 20 nm and lengths up to 2 μm have been synthesized in a simple organic solution by using hydrothermal method. Particularly, these zinc oxide nanostructures has been prepared into single-crystalline prisms or belts with uniform diameters along the entire length. The structure and characteristic of the as-obtained ZnO nanostructures were confirmed by XRD, TEM, HRTEM, and EDX. UV measurements and photoluminescence had been used to characterize the optical properties and confirm the crystal perfection of these ZnO nanomaterials.

Nano Rods

ZnO micro/nano rods were grown　on fluorine doped tin oxide (FTO) substrates by aqueous chemical growth (ACG) using Zn(NO3)2•6H2O and C6H12N4 at low temperature. For comparison, the yield of nanorods on indium-tin-oxide (ITO) substrates with same parameters was also discussed. SEM, TEM, SAED and XRD were utilized to characterize morphologies and structures of ZnO crystals. It was indicated that the temperature and the concentration of the solution significantly leads to the yields of the ZnO. Single-crystalline ZnO micro/nano rods could be synthesized via an aqueous solution route without adding alkali solution at 70°C in large area.
