A simple direct writing method using template‐directed convective self‐assembly is employed to fabricate concentric multi‐ring structures of metallic nanoparticles. The concentric ring‐type nanostructures, combined with a gold film, effectively induce a collective surface plasmon resonance, evidenced by a significant enhancement of the fluorescence intensities and Raman signals. This method opens possibilities for many advanced applications, including biosensing and nanophotonics.
