▎ 摘　　要

A novel strategy toward one-pot hydrothermal synthesis of copper sulfide nanoplates-decorated reduced graphene oxide (RGO-CuS) composites was developed. CuS nanoplates were successfully loaded onto the surface of RGO in the hydrothermal procedure, which was confirmed by transmission electron microscopy, UV-Vis-NIR and Raman spectroscopy. The as-synthesized RGO-CuS composites showed pronounced enhanced optical absorbance in near infrared (NR) region and higher photothermal conversion efficiency than noncomposite GO and CuS nanoplates. The RGO-CuS materials were used in photothermal ablation of cancer cells with a 980 nm laser irradiation and showed improved performance than CuS nanoplates.
