Abstract

A facile method of preparing Au-Ag alloy nanoparticles in organic solvent, with high monodispersity and controlled size from 6 to 13 nm diameter, is described. The localized surface plasmon resonance frequency and size of alloy nanoparticles were controlled by varying both the precursor ratio and surfactant composition. Thus, the plasmon resonance frequency could be tuned by varying composition with little change in particle size.
