“…The surface plasmon resonance is well manifested at position 371.3 eV for sample A3 and less at 371.9 eV for sample A2. This can be classified as the A 1 satellite with the 3.8 eV separation from the 3d 5/2 line and can be identified as a surface plasmon according to Leiro et al (1983). In our case, the energy difference between the plasmon and the Ag 3d 5/2 emission line maximum is 3.7 eV.…”

The synthesis of hybrid silver/zinc oxide (Ag/ZnO) decoration on the cellulose surface is described. The structures were characterized with X-ray photoelectron spectroscopy (XPS) and corroborated with X-ray diffraction and scanning electron microscopy. Silver nitrate and zinc acetate dihydrate were used as soluble raw materials. Hexamethylenetetraamine was used as the precipitating and reducing agent. The surface of a-cellulose was always treated by hydrogen peroxide before synthesis with a relatively mild effect manifested in water contact angle measurement and XPS high-resolution spectra. The Ag/ZnO decoration system was identified as a true nanodispersed metal/semiconductor hybrid with a unique collective plasmonic structure observed on Ag 3d core lines for the first time. A series of experiments with a single precursor solution contributed to the characterization of the interaction of Ag ? and Zn 2? species with the surface and to the description of the reaction mechanism in the mixed precursor solution. In contrast to previous reports, a specific interaction between the cellulose substrate and Zn 2? was observed. No specific non-thermal effects of microwave heating were observed.

“…In both the LT and RT structures, the C1s peak appears at 285.4 eV and the N1s peaks at 398.2 eV. (The two broad peaks appearing at ∼398.5 and 393.0 eV in the N1s spectra of the clean Ag surface are due to bulk plasmon losses 26 ). As discussed in Figure S3 in the supplementary material, 12 the superposition of the XPS peak to the plasmonic losses does not affect the measured binding energy within experimental error.…”

The deposition of tetracyanoethylene (TCNE) on Ag(111), both at Room Temperature (RT, 300 K) and low temperatures (150 K), leads to the formation of coordination networks involving silver adatoms, as revealed by Variable-Temperature Scanning Tunneling Microscopy. Our results indicate that TCNE molecules etch away material from the step edges and possibly also from the terraces, which facilitates the formation of the observed coordination networks. Moreover, such process is temperature dependent, which allows for different stoichiometric ratios between Ag and TCNE just by adjusting the deposition temperature. X-ray Photoelectron Spectroscopy and Density Functional Theory calculations reveal that charge-transfer from the surface to the molecule and the concomitant geometrical distortions at both sides of the organic/inorganic interface might facilitate the extraction of silver atoms from the step-edges and, thus, its incorporation into the observed TCNE coordination networks.

An idea of using nanofilm-nanoparticle-electron donor composites as the energy sources to sub stitute oil and gas has been developed by American, Japanese, and Chinese scientists. The underlying princi ple is as follows: under the effect of visible light, electrons are knocked out from nanoparticles; absorbed by the nanofilm, which acts as a reservoir; and, finally, attached to the donor; then, the cycle is repeated. In this review, the electronic structure, properties, and interactions between all the nanocomposite components, as well as their interaction with the solvent and protective shell, are analyzed. The interactions are shown to reduce the efficiency of a nanocomposite used as a photogalvanic cell.
