- Abstract
We mimic unique honeycomb structure as well as its functions of storing honey and pollen to assemble Au nanoparticle pattern on honeycomb-like Al nanobowl array by utilizing solid state dewetting process. Patterned Au nanoarrays of 'one particle per bowl' with tunable plasmonic bands ranging from the visible to the near-infrared region are fabricated by finely selecting the initial thickness of Au film, the geometry of Al nanobowl array and the thermal treatment parameters. This work presents a powerful approach to assemble Au nanoparticles into high density nanoarrays with superior spatial resolution, offering highly concentrated electromagnetic fields for plasmonic sensor applications.
