Abstract
ZnO production nanostructure using different method: first method, electrochemical deposition on Zn foil using 0.3 M zinc sulfate heptahydrate (ZnSO4·7H2O) and sulfuric acid aqueous solution at a current density of 30 and 35 mA/cm2 for deposition time 40 min at room temperature and second method, Zn foils were thermally oxidized in a conventional tube furnace at a temperature equal range of 700–900 °C in air for 5 h or less in static air to prepared semiconductor nanomaterials ZnO nanorods, nanotetrapods and nanoplane. The XRD diffraction of higher intensity peaks at (101) and (002) miller indices for two methods can be recognized to a hexagonal wurtzite structure unit cell. Surface morphology images with different magnifications which clearly shows that the whole Zn foil and rod substrate obtained ZnO nanosheets, nanotetrapods, nanorods and growth nanoplanes were also found. The length of these nanotetrapods and nanorods lies in the equal range of 1–1.5 µm with an average diameter of 80 nm. It was well known that ZnO nano crystal exhibited two emission peaks. One was located at about 365 nm wavelength (UV luminescence band), and the other peak position at 475 nm wavelength (green luminescence band).
Highlights
In recent years, there has been a great interest in production of transparent conducting oxide (TCO) and transparent oxide semi-conductors for the development of photonic devices and transparent conducting electrodes (TCE) for solar cells [1]

Summary
There has been a great interest in production of transparent conducting oxide (TCO) and transparent oxide semi-conductors for the development of photonic devices and transparent conducting electrodes (TCE) for solar cells [1]. ZnObased nanostructure research has drawn considerable attention in the last few years as a multi-functional material due to its versatile properties like near UV and visible (green, blue and violet) emission, optical transparency, electrical conductivity, piezoelectricity and many other promising applications in electroacoustic transducers, gas sensors, transparent conducting coating materials, photovoltaic devices and optical solar cells [4]. Numerous ZnO nanostructures have been demonstrated, for example, nanowires, nanotubes, nanobelts, nanopropellers, and nanocages [3]. It manifests its applications, especially when approaching the nanoscale size, for example, in the form of one-dimensional nanowires/nanorods/nanotubes or two-dimensional nanoplates/nanosheets, which have been widely accepted as the building blocks for nanodevices.
