Abstract

This paper presents some results on the application of laser ablation in inert gas atmosphere for deposition of nanosized particles. Cu and Ag were deposited in 0-10 mbar Ar atmosphere, then the samples were characterized by TEM and XPS Below 1 mbar for Cu and 2 mbar for Ag island like thin film formation was observed. In Cu above 1 mbar lonely nanoparticles with diameters of 3-4 nm as well as large cluster aggregates were found, instead of the islands. This morphology remained unchanged up to 10 mbar On the contrary, in Ag at 5 mbar individual particles with sizes of 4-6 nm were observed instead of the aggregates, while at 10 mbar particles in the size range of 10 nm became dominant. The observed results may be related to the different decelerating rate of the evaporated Cu and Ag atoms in the Ar atmosphere.
