      Abstract:

      A novel hydrothermal layer-by-layer processing method for the   fabrication of core/alloy nanoparticles with highly tunable   surface plasmon resonance is described. For a model system of   Au/Au(x)Ag(1-x), the processing temperature, alloy composition,   and alloy thickness resulted in unique and tailorable plasmonic   signatures. The discrete dipole approximation and selective alloy   etching were used to correlate this optical response with the   particle morphology and alloy phase ultrastructure.
