“…ZnO was chosen as a material of buffer layer based on several points. Firstly, the technology of obtaining ZnO by the sol-gel method is well studied and simple, and a sol composition based on 2-methoxyethanol has been previously developed, which allows to obtain polycrystalline zinc oxide films with high uniformity and smooth surface [21,22]. Secondly, the coating of different material layers from sols based on a single solvent allows for better adhesion and the quality of interlayer boundaries [23].…”

The obtaining of uniform arrays of silver and gold nanoparticles with a surface density up to 3.3∙109 cm–2 on the zinc oxide buffer layers by sol-gel method is described. The variations of the solution composition and synthesis mode, layers coating and subsequent heat treatment were carried out. The absorption spectra of the obtained samples had a peak near 400–570 nm corresponding to the plasmon resonance in the Ag and Au nanoparticles. Wavelength and shape of Ag and Au nanoparticles plasmon peak varied depending on the synthesis mode: the use of ZnO buffer layers leads to an increase in the intensity of the nanoparticles plasmon peak, the annealing leads to a gradual decrease and broadening of the absorption peak of Ag and mixed Ag and Au nanoparticles arrays, but does not affect the peak of Au nanoparticles.

“…Recently, new functional photonic materials with incorporation of Ag, Au, and Cu nanoparticles (NPs) have been developed to activate the effects of localized plasmon resonance [10,11], while the materials with Fe and Co NPs activate ferroelectric effects [12]. This strategy is used to increase the efficiency of photovoltaics [13], photocatalysis [14] and photodetection [15] devices.…”

“…The present research is a continuation of studies of optical and structural properties, as well as of the processes of silver nanoparticles formation (Ag NP) in a ZnO semiconductor films using the sol-gel method with high-temperature annealing. In our previous research we have shown that this method provides an ordered Ag NP system within the ZnO film due to Ag diffusion [9]. However, since all previous works were dedicated to the study of ordering in structures with a single NP layer, there is an issue of how the NP formation will occur in structures with more than one NP layer, and whether diffusion will take place between the layers.…”

We fabricate the samples with two layers of silver nanoparticles embedded in ZnO film exploring sol–gel method by varying the annealing temperatures. The structural properties of the samples are determined by transmission electron microscopy. The effect of the annealing temperature on the nanoparticles plasmon absorption spectra is studied. Annealing at 570 °C results in a shift of the plasmon absorption maximum from 580 nm to 620 nm, due to an increase in the nanoparticles average size from 63 nm to 74 nm. Increasing the annealing temperature to 650 °C results in a shift of plasmon absorption maximum back to 580 nm due to a decrease in the nanoparticles size to 61 nm. Before annealing, the silver nanoparticles of the upper layer locate on top of the nanoparticles of the bottom layer, however, in the plane of the layers, they are arranged randomly at a distance of 30 to 150 nm from each other. As a result of the annealing, the system tended to be ordered, as a result, the nanoparticles in the layers become to be distributed equidistant at 40–70 nm between them; the nanoparticles of the upper layer tend being located between the nanoparticles of the bottom layer.
