Abstract

Abstract : Au@Cu7 S4 yolk–shell nanoparticles have been prepared via an inward replacement strategy and they exhibit powerful photothermal properties with a heat conversion efficiency up to 63% under 980 nm laser irradiation. Abstract : We report the preparation of Au@Cu7 S4 yolk–shell nanoparticles (NPs) via an inward replacement strategy based on the Kirkendall Effect. Due to the surface plasmon resonance (SPR) effect enhanced absorption in the near-infrared (NIR) region and the unique yolk–shell structure, the Au@Cu7 S4 NPs exhibit excellent photothermal performance with a heat conversion efficiency up to 63% under 980 nm laser irradiation.
