Size Tunable Au@Ag Core–Shell Nanoparticles: Synthesis and Surface-Enhanced Raman Scattering Properties

We describe a simple and efficient methodology for the aqueous synthesis of stable, uniform, and size tunable Au@Ag core–shell nanoparticles (NPs) that are stabilized by citrate ions. The synthetic route is based on the stepwise Ag reduction on preformed Au NPs. The final size of the core–shell NPs...
