Ag7Au6: A 13‐Atom Alloy Quantum Cluster

An alloy cluster containing a 13-atom core, with a composition Ag7Au6(H2MSA)10 (H2MSA=mercaptosuccinic acid) was synthesized from silver clusters by a galvanic exchange reaction. The clusters were characterized by several spectroscopic and microscopic methods. The alloy cluster shows luminescence with a quantum yield of 3.5×10−2 at room temperature. Theoretical calculations for Ag7Au6(SCH3)10 suggest a distorted icosahedral core. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
