Stimuli-responsive luminescent materials with time-dependent color are highly desirable in optical information encryption. In this study, multiple processes achieved by light-responsive afterglow through the strategy of absorption compensation. Based on single-emission band materials, samples could show a change from colored to colorless over several seconds. The possesses high flexibility such that stimulus light and emission can be adjusted conveniently adapt various scenes. It is also beneficial expand capacity complexity A three-color, time-resolved anticounterfeiting, data encryption mode demonstrated. This facile compensation method based light-response may promote development advanced dynamic
