a Normalized photoluminescence (PL, steady state and delayed 10 ms) and mechanoluminescence (ML, prompt and delayed 10 ms) spectra of the host (PC, BPC, and BCPC) crystalline powders. b PL decay profiles of the afterglow emission at 565 nm for PC&PB, BPC&BPB, and BCPC&BCPB (λex = 365 nm). c Time-resolved emission spectra (TRES) mapping of PC&PB, BPC&BPB, and BCPC&BCPB. Inset: Luminescent photographs of the isostructural doping systems under UV on and UV off. d PL (steady state and delayed 10 ms) and ML (prompt and delayed 10 ms) spectra of PC&PB, BPC&BPB, and BCPC&BCPB. Inset: ML images of the isostructural doping systems.
