Fig. 5. Quantification of the temporal response of photothermal effects at the liquid-solid catalyst interface.
a, b Wavelength shifts of typical resonances w/ and w/o CNT coating before and after light switch on, showing the response time of light irradiation (a) and three cycles with light on/off (b). c Real-time wavelength shifts response of HC (99) mode and core mode with increasing light power levels, controlled by filters with transmissivities from 0 to 100%. d The linear relationships between the temperature changes for HC and core modes and the light power level
