Abstract

A dissolution–renucleation process leading to the coalescence of Ag₂S and Au nanocrystals was demonstrated. This unique phenomenon can be applied to extract Au from quantum dot–Au hybrids or Au-containing alloys, providing an effective strategy to investigate the influence of Au on the properties of Au-containing hybrids or alloys.
