Abstract

It was found that long-lived positively charged and neutral silver clusters were formed by the radiation-chemical reduction of Ag+ ions in aqueous solutions containing sodium polyphosphate. The nuclearity of the clusters increased with absorbed dose; then, quasi-metal particles were formed. The process culminated in the formation of silver nanoparticles.
