Abstract
The influence of plasmonic coupling effects between different components in Au NRs@Cu(2-x) Se nanostructures on their characteristics was studied. To this aim, anisotropic Au@Cu(2-x) Se 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.
