“…ZnO is also biocompatible and biodegradable [17], and therefore suitable for medical [18] and environmental applications [19]. Most interestingly, the properties of zinc oxide as a material strongly depend on the dimensionality, size and morphology of the ZnO nanostructures [13,[20][21][22].…”

We modify and optimize a cheap, simple and effective synthesis of zinc oxide nanosized particles by electrodeposition. The core method encompasses the synthesis of ZnO product on the soluble zinc anode of the two-zinc-electrode cell emerged in aqueous NaCl. Resulting particles have the shape of cocoa fruit, thick in the middle and sharp at the edges. They have uniform shape, but broad size distributions with most of the ZnO product 1-2 µm long and 0,5-0,7 µm thick. Thus, auxiliary stabilizers are added to aqueous phase to reduce the size and narrow its distribution in the target product. Here we present the size stabilizing action of four successful stabilizers: urea, polyvinyl alcohol, Triton x-100 and Atlas G3300. All of them reduce particle size and polydispersity. An anionactive surfactant atlas is the most effective, giving an order of magnitude nanorod size reduction.

“…They differ in their approach, cost, and ultimate results. The two-electrode neural aqueous synthesis is simple, green and cheap, gives high yields and allows the current-time control of product quantity [20,30,32,34,[37][38][39]. It is successfully used for the manufacture of ZnO thin films [40].…”

“…Recently there has been observed an enhanced interest on Zinc Oxide (ZnO) based nanostructure because of their large variety of applications mainly in field-effect transistors, piezoelectric nano-generators, photodiode, solar cell, coherent laser transformation, gas sensors etc… [1]. These materials may be applied as photocatalyst and sensors due to their promising piezoelectric and optical and nonlinear optical features [2][3][4][5][6]. Large exciton binding energy of 60 meV, a wide direct band gap about 3.37eV, nontoxic, and a relatively high melting point of 1975 °C, easy device fabrication, high optical transmittance, high thermal conductivity and high electron mobility has always made ZnO as a promising candidate for various applications [1][2][3][4][5][6][7][8][9].…”

“…The properties that can be controlled by template functionality can be structural, topographical, electrical, mechanical, piezoelectrical, adhesive, tribological, catalytic activity [19] or properties connected with the granularity of the film [20][21][22][23]. Additionally, the reflectivity or light scattering properties may be controlled -the latter of which are highly relevant for the fields of optical data storage [24,25] and lithography (where increasingly smaller structures are sought, e.g., in the field of semiconductor nanolithography). Here, the copying of a given structure by self-templating may provide an alternative to conventional replication.…”

We present a promising first example towards controlling the properties of a self-assembling mineral film by means of the functionality and polarity of a substrate template. In the presented case, a zinc oxide film is deposited by chemical bath deposition on a nearly topography-free template structure composed of a pattern of two self-assembled monolayers with different chemical functionality. We demonstrate the template-modulated morphological properties of the growing film, as the surface functionality dictates the granularity of the growing film. This, in turn, is a key property influencing other film properties such as conductivity, piezoelectric activity and the mechanical properties. A very pronounced contrast is observed between areas with an underlying fluorinated, low energy template surface, showing a much more (almost two orders of magnitude) coarse-grained film with a typical agglomerate size of around 75 nm. In contrast, amino-functionalized surface areas induce the growth of a very smooth, fine-grained surface with a roughness of around 1 nm. The observed influence of the template on the resulting clear contrast in morphology of the growing film could be explained by a contrast in surface adhesion energies and surface diffusion rates of the nanoparticles, which nucleate in solution and subsequently deposit on the functionalized substrate.1763
