Photothermal profile of supra-CNDs. Temperature elevations of (a) supra-CND aqueous dispersions with different concentrations under 732-nm laser irradiation (1 W cm−2) compared with pure water, (b) supra-CND aqueous dispersions (100 ppm) under 732-nm irradiation with increasing laser power densities, (c) supra-CND, GO and CND aqueous dispersions (100 ppm) under 732-nm laser irradiation (1 W cm−2) and (d) supra-CND aqueous dispersions with different concentrations under 808-nm laser irradiation (1 W cm−2) compared with pure water. All experiments were conducted at room temperature.
