Cost-Effective and High-Throughput Plasmonic Interference Coupled Nanostructures by Using Quasi-Uniform Anodic Aluminum Oxide

Abstract: Large-area and uniform plasmonic nanostructures have often been fabricated by simply evaporating noble metals such as gold and silver on a variety of nanotemplates such as nanopores, nanotubes, and nanorods. However, some highly uniform nanotemplates are limited to be utilized by long, complex, and expensive fabrication. Here, we introduce a cost-effective and high-throughput fabrication method for plasmonic interference coupled nanostructures based on quasi-uniform anodic aluminum oxide (QU-AAO) nanotemplates… Show more

“…Previously, our group reported interference-plasmonic coupling effects on metal-coated hexagonally ordered AAO (HO-AAO) structures. Since the thickness and pore size of HO-AAO are easily tuned by controlling the 2nd anodization time and pore widening process, we found that our structures facilely changed interference effects at a plasmonic layer, thus resulting in a clear color change and optical absorption [16]. Those structure-dependent optical behaviors, however, are limited by their angle dependency because incident optical sources may not always be oriented normal to the structure.…”
