Effects of Single Platinum Atom Doping on Stability and Nonlinear Optical Properties of Ag 29 Nanoclusters
Résumé
The properties of atomically precise noble metal nanoclusters can be modified by the addition of other metals, which may offer augmented characteristics, making them more suitable for real-life applications. In this work, we report the effects of single-platinum atom doping of a class of atomically precise silver nanoclusters protected by dithiolated ligands on their optical properties both in linear and nonlinear optical (NLO) regimes and on their stability over time. Pt doping of Ag 29 preserves their NLO properties (in particular two-photon excited photoluninescence).
