Fig. 3

a Mechanism of the photochemical reaction triggered by white light to indicate changing information, CU refers to consumption units. b Schematic diagram of recording the afterglow intensity of bipolar PC film with EMCCD (electron-multiplying charge-coupled device). c Afterglow imaging of bipolar PC films with different CU concentration and degree of white light exposure. d Afterglow intensity of bipolar PC films with different concentrations of CU under different white light doses. e Afterglow intensity of bipolar PC film at a CU concentration of 12 mM stored in darkness for different time periods.
