Synthesis of Nanometer-sized (BI)metallic Clusters with a Nuclear Reactor
Abstract
Mono- and heteronuclear clusters were synthesized by irradiating with gamma rays from a nuclear reactor aqueous solutions containing ionic precursors. Ag, Au/Ag and Ag/Pd clusters were produced and characterized by optical absorption and transmission electron microscopy measurements. Electron diffraction measurements show that the clusters have a crystalline fcc structure. Ag and Au/Ag clusters have a lattice parameter which coincides with the bulk. In the case of Ag/Pd clusters, a homogeneous alloy is formed whose lattice parameter closely follows Vegard's law. The cluster size distribution is in the nanometer range, although coalescence processes lead often to large aggregates. Optical absorption spectra are in agreement with previously reported results, when the presence of large aggregates is taken into account.
