While anticounterfeiting systems based on long persistent luminescence (LPL) materials demonstrate a mature trend, the integration of tunable luminescent lifetimes and emission colors in LPL-based remains challenge. Herein, we propose temporal spatial strategy utilizing novel zero dimensional (0D) metal halides, specifically (PBA)3BiCl6:xSb3+ (PBA = 4-Phenylbenzylamine, x 0, 0.05, 0.1, 0.15), which exhibit characteristics. A controllable color transition can be observed from green to white orange by varying excitation wavelength, accompanied different afterglow durations LPL emission. Additionally, various are at delay times. Furthermore, controlled duration is achieved through Sb3+ doping (PBA)3BiCl6, attributed triplet energy transfer (TET) process. noticeable when using mobile phone's flashlight as source, enhancing portability light source. The multifaceted tuning modulation establish foundation for multicolor time-resolved anticounterfeiting, significantly elevating security level advanced portable systems.

Abstract In this study, a simple and rapid strategy is developed for the gram‐scale synthesis of zinc(II) halide complexes with ultralong afterglow under mild conditions. Crystalline, high‐purity are synthesized using N ‐methylbenzimidazole ( Bz ) common zinc salts (ZnX 2 , X = Cl, Br, I) as cheap industrial raw materials by stirring at room temperature atmospheric pressure. By exploiting steric effect terminal‐coordinated halogen ions to regulate arrangements ligands in structure complexes, namely cis ‐butterfly, trans cross ‐arrangement, completely differentiated stacking modes obtained. Zn(Bz)Cl ‐butterfly‐shaped arrangement has longest room‐temperature phosphorescence (RTP) lifetime (505.01 ms 298 K) long up 1.4 s. This study proposes first time use end group coordination fluorophores within resulting considerably improved RTP afterglow, thus providing new platform large‐scale afterglow.
