Optical response of Ag2, Ag3, Au2, and Au3in argon matrices

摘要

We report on the optical response of size selected Ag2, Ag3, Au2, and Au3embedded in argon matrices. Cluster samples were investigatedinsituby excitation, fluorescence, and absorption spectroscopy. The spectra for the dimers are in agreement with previous measurements made on conventionally prepared matrices. Our previously reported spectra of trimers in krypton are confirmed by the argon results. The influence of the matrix gas will briefly be discussed.
