Silver migration between Au38(SC2H4Ph)24 and doped AgxAu38−x(SC2H4Ph)24 nanoclusters†
Abstract
A fast redistribution of metal atoms occurs upon mixing the AgxAu38−x and Au38 nanoclusters in solution, as observed by mass spectrometry. Physical separation of AgxAu38−x and Au38 species by a dialysis membrane prohibits the metal migration, which suggests that collisions between the reacting clusters are at the origin of the observation.
