Understanding Au ∼98 Ag ∼46 (SR) 60 nanoclusters through investigation of their electronic and local structure by X-ray absorption fine structure

Synchrotron radiation-based X-ray absorption fine structure (XAFS) of thiol-stabilized Au ∼98 Ag ∼46 (SR) 60 nanoclusters suggests that Au atoms preferred to occupy the metal core sites while the Ag atoms were mainly on the surface.
