“…Ions, such as Cl − or CH 3 COO − [41], are adsorbed (capping) preferentially on the positive polar face of the (0001) plane. This will limit the crystal growth along the c-axis and redirect the growth in the ( 101 ¯ 0 ) plane, and as a result, a platelet-like ZnO is produced [41,42,44]. It is worth noting that the substrate type has a significant effect on the morphology of the prepared ZnO structures.…”

In this chapter, we review the application of zinc oxide (ZnO) in ultraviolet (UV) sensing and emphasise on the two-dimensional (2D) ZnO structures. The synthesis of 2D ZnO structures, the morphologies, and the photoluminescence emission will be reviewed and highlighted. The performance of the UV sensors based on 2D ZnO structures is explored. The lack in the study of the 2D ZnO UV sensors might be due to the difficulties of controlling the growth of the 2D ZnO compared to the one-dimensional (1D) ZnO structures.

One-dimensional nanostructures hold the most attractive and excellent physiochemical characteristics which exhibit the paramount infl uence on the fundamental and technological nanoelectronic as well as nanophotonic applications. In this review article, we present a detailed introduction to the diverse synthetic procedures which can be utilized for the fabrication of single-, planar-and three-dimensional ZnO nanostructures. More specifi cally, a thorough discussion regarding luminescence characteristics of the one-dimensional ZnO nanostructures is presented for ultraviolet and visible regions. We summarize the room temperature spontaneous emission and stimulated emission along with the interaction of the incident beam with material cavity to produce resonant optical modes and low-temperature time resolved photoluminescence studies. The most recent published results on the white light emitting diodes fabricated with the combination of ZnO nanotubes with p-GaN and ZnO nanorods with p-organic polymers on glass and disposable paper are discussed. Additionally, the signifi cant results on optically and electrically pumped lasers are discussed; along with an overview on the future of ZnO nanostructures based photonic devices.

“…ZnO arrays were electrodeposited on transparent indium tin oxide (ITO) or fluorine doped tin oxide (FTO) covered glass (Pilkington) cathodes in aqueous electrolytes contained ZnSO 4 Phase composition and structure of the deposited films were determined by XRD-method using an X-ray diffractometer DRON-4M with CoK α radiation according to θ-2θ-scheme. Preferable orientations of the films were researched by analytical treatment of the X-ray diffractions by means of obtaining of texture factor P i [11]:…”

“…low processing cost, large scale, no vacuum system need, high deposition speed and no use of toxic gases. Effects of electrolyte formula, namely anionic composition [4] and presence of the different organic additives [6], deposition temperature and deposition time [7] and even gravitational level effects [9] on structure and properties of the electrodeposited ZnO nanowire arrays are studied extensively. Nevertheless, there are only rare attempts to employ a pulsed potential technique for ZnO electrodeposition [10].…”

Abstract:The feasibility of one-dimensional (1D) nanostructured zinc oxide array pulse plating has been presented. An effect of the electrolyte composition, deposition regime and subsequent annealing on structure and optical properties of the electrodeposited ZnO layers has been approved by X-ray diffraction and spectrophotometric analysis. We have determined that for obtaining of ZnO arrays with strong (002) preferable growth orientation in the c-axis direction it is necessary to diminish adsorption of hydrogen and Cl --ions. It has been shown that such conditions are created in electrolyte that contains 0.05 M Zn(NO 3 ) 2 and 0.1 M NaNO 3 during electrodeposition on FTO-coated glass substrates in pulse plating regime with rectangular impulses of cathode potential (20 ms on-time at U on = -1.4 V and 30 ms off-time at U off = -0.8 V). Therefore, in this work we for the first time have demonstrated the successful growth of 1D ZnO nanostructures by pulse plating without using of templates. The novel electrodeposition technique gives possibilities for the manufacture of the ZnO arrays suitable for solar cells with extra thin absorbers.
