The fluorescence signal shown in the bottom panel is split into the dye (red) and dot (blue) contributions. The inserts present the time-dependent localizations of the exciton of the dot and the dye, with the green circle showing the current moment in time. The movie shows evolution after a short pulse excitation for the time interval from 0 to 10 nanoseconds. For details please see Fig. 3 of the following paper:
