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.
