Near-Field Optical Properties of Fully Alloyed Noble Metal Nanoparticles

Abstract

The near‐field optical response of metal alloyed nanostructures obtained via a physical deposition method is presented. Dewetting of metallic thin films is implemented to produce fully alloyed AgxAu1−x nanoparticles and show how the chemical composition affects their optical response. These results demonstrate the potential for realizing alloyed nanostructures with engineered optical properties for applications ranging from nanophoto­nics to sensing.
