Abstract

Luminescent AgAu alloy quantum clusters are synthesized by the galvanic reduction of polydisperse plasmonic silver nanoparticles. Selective and tunable luminescence quenching by CuII ions depends on the solvent and protecting ligands. The tunability is achieved by variation of the metallophilic interactions between the AuI ions of the cluster and CuI ions formed by reduction by the cluster core.
