大尺寸硫醇配体保护金团簇的激发态动力学研究
Excited-State Dynamics of Large-Sized Thiolate-Protected Aun (n>100) Nanoclusters
摘要
Abstract
Gold nanoclusters (size <2.2 nm) bridge metallic gold nanoparticles and single gold atoms, playing a crucial role in revealing the origin of surface plasmon resonance and metallic bonding. Ligand-protected gold nanoclusters provide a suitable platform to under-stand metal to non-metal transitions while the excited-state dynamics of gold nanoclusters in the transition regime remain elusive. In this minireview, I summarize the excite-state dynamics of large-sized Aun (n > 100) nanoclusters and compare them with those of plas-monic gold nanoparticles. By looking into the electron and vibration dynamics of a series of thiolate-protected gold nanoclusters in the transition regime, the electronic structures of these nanoclusters are further discussed. A deeper understanding of the mechanism of elec-tron relaxation and energy dissipation of large-sized gold nanoclusters will be of great help to connect the optical properties of metal clusters and nanoparticles, which will further promote the design of those functional nanomaterials.关键词
