a, Time-slices of neat NODIPS-An with a pump excitation at 410 nm (ΔmOD, change in thousandths of optical density). b, Kinetic plots of neat NODIPS-An GSB (465–480 nm) and ESA (520–540 nm). The kinetic trace is fitted with a Gaussian convoluted with a biexponential function (red line). c, Time-slices of a device with pump excitation at 670 nm. d, Kinetic trace of the device ESA (550–580 nm). The trace is fitted with Gaussian convoluted biexponential and an offset. Shaded areas in a and d correspond to the integrated areas tracked in the kinetic plots. The fitting results along with errors and relative contribution are displayed in the kinetic plots.
