Stimuli-Responsive Afterglow from Luminescent Liquid Crystal Elastomers.

ABSTRACT: Stimuli-responsive luminescent polymeric materials which combine afterglow emission with mechanical flexibility and adaptability to external stimuli are well-suited for dynamic optical devices, encoding, anticounterfeiting, and soft robotics. However, current systems rely on static matrices and organic phosphors, which limit their afterglow duration, flexibility, processability, and responsiveness to various stimuli. Here, an active glow luminescent system for encoding, signaling, and tracking in dark environments by integrating inorganic ultralong afterglow phosphors with adaptive liquid crystal elastomer actuators is demonstrated. The resulting material exhibits ultralong emission (up to 1200 s) in the dark, enabling reprogrammable information encryption and reversible scattering-to-tran
