Plasmonic nanostructures have been studied for many practical applications such as biosensing and optical-thermal conversion due to their unique optical properties. As plasmonic materials, not only pure precious metals but also alloys can be used to tune the optical properties. Recently, specific localized plasmon resonance of phase-separated Ag-Cu nanoparticles has been reported. In this presentation, I report on the optical properties of Ag-Cu nanoparticles aligned in the phase-separation direction and arranged in a hexagonal lattice.
