Nonlead low-dimensional halide perovskites attract considerable attention as X-ray scintillators. However, most scintillation screens exhibit pronounced light scattering, which detrimentally reduces the quality of imaging. Herein, we employed a simple and straightforward solvent-free melt-quenching method to fabricate large-area zero-dimension (0D) antimony-based perovskite transparent medium, namely (C

Abstract Luminescent metal halides are attracting growing attention as scintillators for X-ray imaging in safety inspection, medical diagnosis, etc. Here we present brand-new hybrid Eu(II)-bromide scintillators, 1D type [Et 4 N]EuBr 3 ·MeOH and 0D [Me N] 6 Eu 5 Br 16 ·MeOH, with spin-allowed d -4 f bandgap transition emission toward simplified carrier transport during scintillation process. The 1D/0D structures edge/face -sharing [EuBr ] 4− octahedra further contribute to lowing bandgaps enhancing quantum confinement effect, enabling efficient performance (light yield ~73100 ± 800 Ph MeV −1 , detect limit ~18.6 nGy s afterglow ~ 1% @ 9.6 μs). We demonstrate the 27.3 lp mm resolution by embedding Eu(II)-based into AAO film. Our results create new family of low-dimensional rare-earth-based related optoelectronic applications.

Abstract Although the luminescent performance of organic–inorganic metal halides (OIMHs) have obtained significant advances, achieving intrinsic water‐stable OIMHs remain a substantial challenge due to fragile ionic nature hybrid halide structure. To overcome these challenges, structural design strategy is proposed that involves use highly hydrophobic cations as protective layer improve water stability OIMH. Herein, an aprotic trimethylsulfoxonium [TMSO] + selected cation and successfully assemble two new manganese based (TMSO)MnCl 3 (TMSO)MnBr through facile solid liquid phase reaction methods. Remarkably, exhibit strong red light emissions with high quantum yields recorded at 86.1% 53.4%, respectively, originating from octahedral [MnX 6 ] 4− one‐dimensional (1D) − chain. Most significantly, present extraordinary stabilities toward continuous corrosion by humid air, water, acid‐aqueous solution for more than one month, suggesting promising application prospects in extreme chemical environments. In‐depth Hirshfeld surface calculations demonstrate ultrahigh water‐stability benefits abundant hydrogen bonds electrostatic interactions between ions, which provides underlying insight into mechanism. This enhancement represents breakthrough engineering rationally
