DPBF used to check the ROS produced in the FRET process of AlPcS-QDs. (a) Fluorescence intensity decreasing of DPBF (12 μM) in AlPcS-QD (0.1 μM) aqueous solution with the irradiation time of a 532-nm laser (16 mW). Excitation, 405 nm. (b) The comparison of DPBF photo-degradations of AlPcS-QD (0.1 μM), AlPcS (10 μM) and QD (0.1 μM) aqueous solutions under the irradiation at 532 nm. The protection effect of NaN3 (the quencher of 1O2) on DPBF degradation was demonstrated.
