Doping Au25 nanoparticles using ultrasmall silver or copper nanoparticles as the metal source

Abstract

Doped metal nanoparticles have attracted extensive interest in recent years, and developing novel doping strategy (especially an atomically monodisperse doping strategy) is seriously required in order to insightfully understand the role of foreign metal atom(s) and widely explore the potential application of such intriguing materials. Herein, the reaction between heterogeneous metal nanoparticles is demonstrated, and this could provide a unique strategy to synthesize doped nanoparticles, including atomically mono-disperse doped nanoparticles.
