“…Ultimately, the growth terminates when the temperature is below to the eutectic temperature of the catalyst alloy, or the reactant is no longer available. The VLS growth mechanism of ZnO nanorods is shown schematically in Figure 3 [74]. Based on the relationship among major parts of growth system, a conceptual model has been summarized in Figure 4.…”

Zinc Oxide (ZnO) nanomaterials have received broad attention thanks to their distinguished performance in electronics, optics and photonics. Due to the novel applications in optoelectronics, sensors, transducers and biomedical sciences, ZnO materials have become a leading edge in nanotechnology. Therefore, the properties of ZnO nanostructures potential for applying in biotechnology are marked along with the relevant common growth mechanism aim to provide the vital information about the growing field related to nano-ZnO in the biomedical system with environmental friendly nature and biocompatibility.

“…Zn on the surface of the Zn substrate is further oxidized from the oxygen to form ZnO nanorods on the substrate (Pei, Zhao, & Tan, 2010). While Zn atoms attached to the ZnO nuclei edges, the oxidization process causes lateral growth of ZnO nuclei (Hejazi, Hosseini, & Ghamsari, 2008;Hou et al, 2009). Figure 1 (a) shows that the ZnO nanostructures grown with growth time of 0.5 h have low density all over the seed, nonhomogeneous distribution of the ZnO NRs.…”

ABSTRACT:Vertically aligned ZnO nanorods arrays were synthesized on glass substrates. ZnO seed layers were prepared on glass substrate by RF Sputtering technique. ZnO nanorods synthesized using low-cost chemical bath deposition method at low temperature (95 ºC). The effect of the different growth time such as (0.5, 1, 2, 3, 4 and 5) h on the morphology, elemental chemical composition and structure of the ZnO nanorods were obtained systemically, and tested by Field emission scanning electron microscopy (FESEM), Energy dispersive analysis (EDX), and XRD measurements. The results found that the ZnO nanorods with hexagonal wurtzite structure grow vertically on the glass substrates. Most of the prepared samples have strong and sharp (002) peak intensities and the diffraction peaks (002) become higher and narrower as growth time increasing, obtaining that the ZnO crystalline quality became better with growth time increasing. The growth rate was decreases with increasing growth time, and the high aspect ratio was found at 4 h as a growth time. The size, length and crystalline size of the ZnO nanorods increase with increasing growth time. Furthermore the ZnO nanorods vertically grow at (002) direction along the c-axis on the glass substrate, with elementary chemical compositions of zinc and oxygen only for all prepared samples.

“…Many one dimensional (1D) nanostructures, such as ZnO [1,2], In 2 O 3 [3], SnO 2 [4], ITO [5] and TiO 2 [6] have attracted great attention in recent years due to their potential applications in electronics and optoelectronic devices. One of the prominent metal-oxide materials, ZnO has been intensely studied for potential applications in electronics, optoelectronics and piezoelectricity [7].…”
