Persistent phosphor has emerged as a promising candidate for information storage due to rapid accessibility and low-energy requirements. However, the low capacity limited its practical application. Herein, we skillfully designed developed NaGdGeO4:Pb2+,Tb3+ stimulated by trace doped Sm3+. As expected, this demonstrates larger carrier than traditional commercial SrAl2O4:Eu2+,Dy3+ phosphors superstrong thermostimulated luminescence (TSL) that is three times greater photoluminescence (PL) intensity (PL efficiency, 17.3%). A mechanism of enhanced controllable TSL proposed based on electron-hole defect pair structure. We further present high-throughput optical data recording in five dimensions single fluorescent film layer. The findings described here provide not only universal approach constructing materials but also new paradigm future generation technology.

Abstract Multi‐stimuli‐responsive materials have received widespread attention in the field of adaptive due to their ability adapt changes environment. However, fabricating multiple stimuli into a single component crystal still remains challenging. In this study, polymorphic elasto‐plastic Schiff‐based displaying morphology‐dependent photomechanical motions is designed and investigated. Both Form I II it exhibit dual plasticity elasto‐plasticity along different facets, which attributed slidable separating layers. Moreover, retains its elastic bending even after being plastically twisted, owing well‐maintained strong π–π interactions, whereas can not twist without fractures. addition, including jumping, twisting are realized by adjusting morphologies, while lacking response ultraviolet light irradiation. Theoretical calculation analysis reveals that lattice deformation induced photoisomerization driving forces for motions. Furthermore, reversible luminescence switching behaviors upon acid‐base fumigation as well heating. The synergistic multi‐stimuli‐responsive mode based on heat, acid, solvent provides an alternative path multi‐mode information encryption.

Room-temperature phosphorescence (RTP) from organic ionic crystals mainly related to molecular packing has attracted growing attention over a wide range of advanced applications. However, limited research focused on improving the RTP performance materials in their aggregated state. Herein, we utilize layer-by-layer self-assembly ammonium chloride salts enhance macroscopic and increase lifetime by 1–2 orders magnitude. Especially, millimeter-sized large crystal exhibits an obvious emission (insensitive air) with ultralong 1886 ms, exceeding most counterparts. Molecular dynamics simulations reveal that compact intermolecular stacking isolates oxygen molecules phenyl groups (distributing spin population triplet state), which effectively suppresses quenching for crystals. Furthermore, other also confirm such macrocrystal-sized dependence lifetimes. This work provides effective crystallization strategy realize emission, along extensive modulation luminescence potential time-gated encryption.
