Anisotropic dual-plasmonic hetero-nanostructures with tunable plasmonic coupling effects

Abstract

The influence of plasmonic coupling effects between different components in Au NRs@Cu_2−xSe nanostructures on their characteristics was studied. To this aim, anisotropic Au@Cu_2−xSe hetero-nanostructures with well-controlled design and optical properties were obtained. The LSPR bands of gold and copper selenide are superpositioned in the NIR region, resulting in superior photocatalytic properties of the nanostructures.
