Herein, we synthesized series CDs by self‐crosslinking carbonization precursor. The resultant were luminescent exhibited bright, micro‐second afterglow lifetime. To increase the RTP, second microwave processing step was used coat with polyvinyl alcohol (PVA), polyacrylamide (PAM), or tetraethyl orthosilicate (TEOS), producing CDs@PVA, CDs@PAM, CDs@TEOS composites. core–shell structure acted enhance crosslinking at surface boost creating abundant energy levels intersystem crossover. In situ X‐ray photoelectron spectroscopy verified electron transfer during luminescence. Finally, present design rule can tune quantum yields lifetime CDs, based on effective stabilization triplet excited states through extent strength cross‐linking.
