Figure 5.

(a) The photothermal response of SDBS-Ag2Se aqueous dispersion (2 mL, 0.5 mg/mL) under a pulse of laser irradiation (1.66 W, 980 nm). (b) Plots of cooling time (after 20 min) versus negative natural logarithm of the driving force temperature (-ln/θ) obtained from cooling stage as shown in (a). SDBS-Ag2Se (c) and CTAB-Ag2Se (d) aqueous dispersion photothermal cycle diagram.
