Figure 5.

Time‐resolved photoluminescence (TR‐PL) decay kinetics of F8BT nanoparticles excited at 355 nm and probed at 542 nm, measured via time‐correlated single‐photon counting (TCSPC). The F8BT nanoparticles prepared with various photocrosslinkers were dispersed in H₂O with ascorbic acid (pH 4, buffer NaOH). All nanoparticle solutions were prepared with an absorbance of 0.2 at the excitation wavelength.
