▎ 摘　　要

A novel reduced graphene oxide-copper sulfide nanoplates (rGO-CuS) composite with photothermal property was synthesized via one-pot hydrothermal method. Structure and morphology of the as-synthesized rGO-CuS nanocomposite were confirmed by transmission electron microscopy (TEM), UV-Vis-NIR and Raman spectroscopy. The rGO-CuS nanocomposite showed enhanced optical absorbance in near infrared region and higher photothermal conversion efficiency than graphene oxide (GO) and CuS nanoplates. The rGO-CuS nanocomposite was further used to photothermal ablation of cancer cells and cancer tissue under a 980 nm laser irradiation and showed improved performance than CuS nanoplates and GO.
