1. A plasmonic substrate comprising a layer of graphene and a plurality of discrete, individual transition metal chalcogenide nanodomes distributed on a surface of the layer of graphene, each nanodome surrounded by bare graphene, wherein each nanodome does not comprise metal nanoparticles on its surface and the surface of the layer of graphene does not comprise metal nanoparticles, and further wherein the transition metal chalcogenide nanodomes are WS₂nanodomes.
