Ultra-narrow red-emitting carbon quantum dots with a high PLQY are rationally synthesized for NIR-II triggered two-photon bioimaging.

A series of room-temperature composites were synthesized by embedding polyaniline carbon dots in hydrogen-bonded polymer matrices. Adjustable RTP lifetime are realized, enabling time-resolved anti-counterfeit and data encryption patterns.

Stimuli-responsive films with dynamic long afterglow feature have received considerable attention in the field of optical materials. Herein, we report the unique dynamic ultralong room temperature phosphorescence (URTP) in flexible...
