Optical Materials: Gold Binary‐Structured Arrays Based on Monolayer Colloidal Crystals and Their Optical Properties (Small 12/2014)

Gold binary-structured ordered arrays, built of the hexagonally arranged nanoshells and nanorings, are fabricated based on non-shadow deposition on dualistic monolayer colloidal crystal. On page 2374 W. Cai and colleagues show how such arrays exhibit tunable surface plasmon resonance properties of gold nanoshells and the strong electromagnetic field enhancement effects of gold nanorings, as well as a promising potential for the substrate of surface enhanced Raman scattering-based devices.
