Abstract:Considerable progress has been made in the synthesis and structural characterization of metal nanoclusters (NCs), but the ligandinduced electron−phonon coupling-dependent ultrafast carrier dynamics is still in its infancy. Here, we have employed a new synthetic strategy for the preparation of Ag 21 (CHT) 5 (DPPB) NCs with 7% photoluminescence (PL) quantum yield (QY). Such high QY is discovered to evolve from the intracluster interactions between 1,4-bis(diphenylphosphino)butane (DPPB) and cyclohexanethiol (CHT… Show more
In this article, the main focus is to employ a new synthetic strategy to prepare atomically precise Ag nanoclusters (NCs) and unveil the critical role of the solvents in the...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
