“…In the literature, the most widely used template is probably AAO due to its simplicity and capability of large area fabrication [128]. After nanowire growth, the template can be chemically dissolved and leaving behind the free standing nanowires.…”

One-dimensional (1D) ZnO nanostructures have been studied intensively and extensively over the last decade not only for their remarkable chemical and physical properties, but also for their current and future diverse technological applications. This article gives a comprehensive overview of the progress that has been made within the context of 1D ZnO nanostructures synthesized via wet chemical methods. We will cover the synthetic methodologies and corresponding growth mechanisms, different structures, doping and alloying, positioncontrolled growth on substrates, and finally, their functional properties as catalysts, hydrophobic surfaces, sensors, and in nanoelectronic, optical, optoelectronic, and energy harvesting devices.

“…The blueshift of the visible emission band with the increase of laser power implies that the emissions are likely from donor-acceptor (D-A) pairs because one of the characteristics of D-A recombination is a shift to higher energy as the excitation intensity increases. [18,19] It may be induced by the shift of carrier position from deep level state to shallow level state which is caused by heating activation, and the increase of combine energy makes the visible emission bands persist blueshift.…”

Simple and low cost solution synthesis method was used to synthesise ZnO nanorods. Dodecyl benzene sulfonate was used to control the growth process and monodispersed nanorods with diameters in the range of 25 to 44 nm were obtained. X-ray diffraction, transmission electron microscopy and high resolution transmission electron microscopy measurements demonstrate the structure and morphology of the products. Laser power-and temperaturedependent photoluminescence (PL) experiments confirm the good ultraviolet emission characteristics. Short exciton lifetime feature relevant to thin nanorods was examined by time-resolved PL. Good optical quality and the size characteristics of the obtained products are discussed.

“…This method is relatively straightforward [4] with controlled diameter, cost efficient and allows the duplication of complex topology present on the surface a template in a single step [5,6]. The method typically operates at ambient temperatures and pressure as well as can be used for mass production of nanostructures with controlled geometry and morphology [2,[7][8][9]. Additionally, among templates, Anodic Alumina Oxide (AAO) templates are the most widely used due to its effective medium for synthesis of metallic nanowires.…”

Abstract.Authors have investigated the influence of the stabilizer (Boric Acid) concentration during the template-assisted electrochemical deposition of Nickel (Ni) nanowires in Anodic Alumina Oxide (AAO) templates. The synthesis was performed using Ni Sulfate Hexahydrate (NiSO 4 .6H 2 O) as metal salts and Boric Acid (H 3 BO 3 ) as a stabilizer. The mixture of both solutions creates electrolyte and utilized for the electrochemical deposition of Ni nanowires. During the experiment, the boric acid concentration varied between 5 g/L, 37.5 g/L and 60 g/L with a deposition temperature of 80 °C (constant). After the electrochemical deposition process, AAO templates were cleaned with distilled water before dissolution in Sodium Hydroxide (NaOH) solution to obtain the freestanding Ni nanowires. Physical properties of the synthesized Ni nanowires were analyzed using Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive Spectroscopy (EDX) and X-ray Diffraction (XRD). The physical properties of obtained Ni nanowires has eloborated by taking into account the effect of boric acid concentration on the surface morphology, growth length, elemental composition and crystal orientation crystal of the synthesized nickel nanowires. The finding exposes that the boric acid concentration does not influence all aspects in the physicals properties of the synthesized Ni nanowires. The boric acid concentration did not affect the surface texture and crystal orientation. However, shorter Ni nanowires obtained as the concentration of boric acid increased.
