Trianionic gold clusters

چکیده
Using Penning-trap experiments and a shell-correction method incorporating ellipsoidal shape deformations, we investigate the formation and stability patterns of trianionic gold clusters. Theory and experiment are in remarkable agreement concerning appearance sizes and electronic shell effects. In contrast to multiply cationic clusters, decay of the trianionic gold clusters occurs primarily via electron autodetach-ment and tunneling through a Coulomb barrier, rather than via fission.

Formation and stability patterns of silver dianionic and gold trianionic clusters are investigated with Penning-trap experiments and a shell-correction method including shape deformations. The theoretical predictions pertaining to the appearance sizes and electronic shell effects are in remarkable agreement with the experiments. Decay of the multiply anionic clusters occurs predominantly by ele...
متن کاملInvestigation of structural and electronic properties of small Au n Cu m (n+m≤5) nano-clusters for Oxygen adsorption
In this study, the structures, the IR spectroscopy, and the electronic properties of AunCum (n+m≤5) bimetallic clusters were studied and compared with those of pure gold and copper clusters using the generalized gradient approximation (GGA) and exchange correlation density functional theory (DFT). The study of an O2-AunCum system is important to identify the promotion effects of each of the two...
متن کاملDesign Principles of Inert Substrates for Exploiting Gold Clusters’ Intrinsic Catalytic Reactivity
Ultralow stability of gold clusters prohibits the understanding of their intrinsic reactivity (that is vital for revealing the origin of gold's catalytic properties). Using density functional theory including many-body dispersion method, we aim to ascertain effective ways in exploiting gold clusters' intrinsic reactivity on carbon nanotubes (CNTs). We find that the many body van der Waals inter...

متن کاملBiocompatible glutathione capped gold clusters as one- and two-photon excitation fluorescence contrast agents for live cells imaging.
The one- and two-photon excitation emission properties of water soluble glutathione monolayer protected gold clusters were investigated. Strong two-photon emission was observed from the gold clusters. The two-photon absorption cross section of these gold clusters in water was deduced from the z-scan measurement to be 189 740 GM, which is much higher compared to organic fluorescent dyes and quan...
