Abstract
Bimetallic Ag—Pd clusters have been synthesized by radiation-induced reduction of aqueous solutions of metal sulfate salts with different AgI/PdII ratios in the presence of polyacrylic acid. The mixed clusters have been characterized by TEM and UV-visible spectra. The evolution of the optical absorption spectrum with the dose absorbed and the electron diffractograms support the conclusion of the formation of an intimately alloyed cluster of AgxPd1-x. The maximum wavelengths of the experimental absorption spectra at variable x coincide with those calculated from the electron density in an alloyed cluster.
