Abstract:
The extinction spectra of size-selected, supported Ag20 and Ag55 clusters have been measured with surface cavity ring-down (s-CRD) spectroscopy under ultrahigh vacuum (UHV) conditions. A single plasmonic resonance around 3.2 eV is observed. The reaction with benzenethiol shifts the localized surface plasmon resonance (LSPR) by ≈0.3 eV to lower energies, which is attributed to an increased dielectric function of the surrounding medium as well as to a reduction of the free-electron density i...     »
