Fig. 3From: Photogenerated reactive oxygen species and hyperthermia by Cu3SnS4 nanoflakes for advanced photocatalytic and photothermal antibacterial therapyA–C Infrared thermal images and corresponding photothermal heating curves of pure water and aqueous dispersions of Cu3SnS4 at different Cu3SnS4 concentrations under continuous irradiation by a 808 nm laser with a power density of 2.5 W cm−2. D, E Photothermal heating curves of aqueous dispersions of Cu3SnS4 by a 808 nm laser with varied power density. F Temperature changes of Cu3SnS4 aqueous dispersions over nine cycles of irradiation/cooling processes. G The temperature profile of Cu3SnS4 aqueous dispersions irradiated with a 808-nm laser, followed by natural cooling after the laser was turned off. H Determination of the system time constant using linear regression of the cooling profile shown in (G). I Cu ions release from the Cu3SnS4 in PBS (pH 7.4) in the presence or absence of the NIR irradiationBack to article page
