Doubly Charged Silver Clusters Stabilized by Tryptophan: Ag4~(2+) as an Optical Marker for Monitoring Particle Growth

摘要

Metal clusters can serve as ultimate building blocks for nanometer-scale devices because of their unique optical and electronic properties, which are size and structure depen-dent. However, an important issue for optical and electronics applications is the influence of charges that can affect the formation and the electronic properties of such nano-systems.
