Plasmonic twinned silver nanoparticles with molecular precision
Abstract
Determining the structures of nanoparticles at atomic resolution is vital to understand their
structure–property correlations. Large metal nanoparticles with core diameter beyond 2 nm
have, to date, eluded characterization by single-crystal X-ray analysis. Here we report the
chemical syntheses and structures of two giant thiolated Ag nanoparticles containing 136 and
374 Ag atoms (that is, up to 3 nm core diameter). As the largest thiolated metal nanoparticles
crystallographically determined so far, these Ag nanoparticles enter the truly
metallic regime with the emergence of surface plasmon resonance. As miniatures of fivefold
twinned nanostructures, these structures demonstrate a subtle distortion within fivefold
twinned nanostructures of face-centred cubic metals. The Ag nanoparticles reported in this
work serve as excellent models to understand the detailed structure distortion within twinned
metal nanostructures and also how silver nanoparticles can span from the molecular to the
metallic regime.
