Abstract

An anisotropic Ag@Au nanostructure is fabricated via physical vapor deposition of gold at oblique incidence onto a glass substrate with a preformed silver nanoparticle array. Utilization of silver nanoparticles as a scaffold for subsequent gold deposition makes it possible to control the size and shape of the gold capping layer. The obtained Ag@Au nanostructures are characterized by adjustable absorption bands and linear dichroism. The proposed technique provides for new opportunities in creation of plasmonic nanoparticles with targeted optical characteristics for applications in nanophotonics.
