Photothermal conversion behaviors and photostability of BPBBT NPs. a–d Photothermal effect of BPBBT NPs at different concentrations under an 808-nm light irradiation with different power densities. e Normalized fluorescence intensity of BPBBT NPs solutions (50 µM of BPBBT) at the maximum emission wavelength over time following an 808-nm laser irradiation with different power densities. f Plot of I/I0 versus the irradiation time. I0 and I are the maximal NIR absorbance of BPBBT NPs solutions (50 µM of BPBBT) before (0 min) and after laser irradiation, respectively
