Simultaneous control of morphology, phase and optical absorption of hydrophilic copper sulfide-based photothermal nanoagents through Cu/S precursor ratios

Simultaneous control of morphology, phase and optical absorption of copper sulfides has been realized by adjusting Cu/S precursor ratio, and the resulting CuS nanoparticles prepared from Cu/S precursor ratio of 1/1 exhibits excellent photothermal conversion performance under the irradiation of 980 nm laser.217
