Continuous modulation of electronic structure of stable thiolate-protected Au25cluster by Ag doping

Abstract

The effect of Ag doping on the electronic structure of a stable thiolate-protected Au₂₅ cluster (Au₂₅(SR)₁₈) was studied by measuring the optical spectra of Au_25−nAg_n(SC₁₂H₂₅)₁₈ (n = 0–11) and the results reveal that the electronic structure of Au₂₅(SC₁₂H₂₅)₁₈ is sensitive to Ag doping and is continuously modulated by incorporation of Ag atoms.
