Deposition of Bimetallic Au/Ag Clusters by the Method of Laser Deposition of Nanoparticles from Colloidal Systems

摘要

A method of formation of bimetallic clusters on the surface of optically transparent media is proposed. Nanoparticles of noble metals were obtained by laser ablation into a liquid. Clusters were formed by means of colloidal deposition of nanoparticles. Cluster morphology after deposition was studied by means of atomic force and scanning electron microscopy. We demonstrate transformation of the transmission spectrum of obtained structures before and after laser-induced aggregation.
