Abstract

Luminescence multiplexing shows promising application prospects in information security, yet even outstanding time division multiplexing can only carry limited luminescence information. Time–space division multiplexing can greatly expand the information capacity by simultaneously transferring luminescence information in both time and space dimensions. Herein, time-dependent polychrome stereoscopic luminescence system has been successfully developed by designing a 3D luminescence system based on resonance energy transfer (RET), in which afterglow lifetime easily regulated carbon dots-in-zeolite composites are used as energy donors and multicolor fluorescence quantum dots (QDs) as energy acceptors. Taking perovskite QDs (PeQDs) as example, by matching the energy donors with different afterglow lifetimes and the energy acceptors with different fluorescence colors, tunable afterglow emission of PeQDs with wavelength within 463–614 nm and lifetime within 232–1500 ms can be realized, in which the maximal RET efficiency reaches 95%. As a proof of concept, such novel luminescence system that carries eight layers of luminescence information involving four dimensions (time and 3D space) is successfully applied in advanced time–space division multiplexing. This work opens a new perspective for the application of time-space integrated luminescence systems in advanced information multiplexing.
