Silver nano particle formation on Ar plasma : treated cinnamyl alcohol

Metastable induced electron spectroscopy, ultraviolet photoelectron spectroscopy, X-ray photoelectron spectroscopy, and atomic force microscopy are employed to study the adsorption of silver on cinnamyl alcohol films prepared on Au(111) substrates by thermal evaporation. Additionally, the impact of an Ar atmosphere dielectric barrier discharge plasma applied to the cinnamyl alcohol film preliminary to the Ag adsorption is investigated. In both cases silver nano particles with an average diameter of 9 nm are formed. These particles do not interact chemically with the underlying cinnamyl alcohol film. We do not find any influence of the preliminary Ar plasma-treatment on the adsorption behavior at all

Adsorption of silver on glucose studied with MIES, UPS, XPS and AFM

The adsorption behavior of silver atoms on a glucose film and their interaction was investigated by metastable induced electron spectroscopy (MIES), ultraviolet photoelectron spectroscopy (UPS) and X-ray photoelectron spectroscopy as well as atomic force microscopy. Glucose is found to form micro droplets on gold substrates with typical diameters/dimensions of about 400 nm. The discussion of the valence band structures is carried out in comparison to various model systems. The adsorbed silver atoms on top of the glucose have been found to form silver nanoparticles that get encapsulated by a large film of glucose. Furthermore, the reduction of the glucose in the presence of these silver particles is observed. This effect is discussed with the most probable origin of the reduction being the charging by electron spectroscopy
