Advanced Science, EarlyView.An irreversible acid‐responsive radioluminescence memory scintillator, Zn1.3Ga1.4Ge0.3O4:Cr3+@Zn2GeO4:Eu3+ (ZGGO@ZGO), is developed in this work. The engineered dual‐layer security system composed of ZGGO@ZGO and ZGO achieves a combined effect of visual misdirection and sequential logic gates requiring acid treatment and CCD detection, significantly ...

Halide‐Exchange Arrest Enables Reabsorption‐Free CsPbCl3/CsPbI3 Perovskite Core/Shell Nanocrystals
Advanced Science, EarlyView.Achieving large Stokes shifts in perovskite nanocrystals is challenging due to halide mobility that disrupts stable core–shell structures. Using CdCl2 passivation, this work stabilizes CsPbCl3/CsPbI3 heterostructures, yielding a ≈1.2 eV Stokes shift, high quantum yield, and fast exciton transfer, enabling reabsorption‐free emitters for advanced ...

Advanced Science, EarlyView.Deuterated MOFs in this work exhibited unprecedented giant luminescence isotope effect via O─H oscillator suppression, achieving maximal solid‐state materials emission enhancement. This yields significantly improved X‐ray detection sensitivity and imaging resolution, marking the first integration of MOFs with isotopic luminescence and opening new ...

Advanced Science, EarlyView.A solvent‐free, open‐mill shear protocol nucleates 2.6 nm CsPbBr3 QDs uniformly within brominated butyl rubber. The emitters showed 91% PLQY, 1189 ns lifetime, and > 90% retention after 30‐day ambient storage and water immersion, respectively. Board‐to‐board forms 17 × 17 cm2 flexible films for 132% NTSC white LEDs, scintillators, and stretchable ...

Advanced Science, EarlyView.This bio‐based chiral luminescent system exhibit photo‐activated CPRTP by anchoring arylboronic acids to hydroxypropyl cellulose (HPC) matrix. Notably, by controlling the drying kinetics, dynamic switchable CPRTP with opposite handedness can be obtained due to a balance of photonic bandgap (PBG) effect and chirality transfer effect induced by the HPC ...

Advanced Electronic Materials, EarlyView.Here we explore the use of lead‐free metal halide perovskites in lithium ion batteries. Cesium zinc chloride and bromide both show reasonable discharge capacities and high stability compared to lead based perovskites. ABSTRACT Halide perovskites have recently gained attention for use as electrode materials in lithium‐ion batteries. However, lead halide
