(a) The concentration-dependent temperature elevation; (b) a time-dependent increase in the temperature; (c) photothermal effect of GNR-PEG-CDs; (d) the time constant for heat transfer from the solution is determined by applying the linear time data from the cooling stage in (c) versus the negative natural logarithm of the driving force temperature. Samples were carried out under 808 nm (1.5 W cm−2) irradiation.
