Abstract
Monodisperse AuAg alloy nanoparticles (NPs) are made from core/shell Ag/Au NPs through Au and Ag diffusion in oleylamine. The composition of the alloy NPs is controlled by the Au shell thickness and the plasmonic absorptions can be tuned from 520 to 400 nm (see image). These alloy NPs have great potential as optical probes for biosensing and bioimaging, or as catalysts for CO oxidation.
