Abstract Developing stable and environmentally friendly metal halide electroluminescent materials is highly desirable. Lead‐free hybrids with ns 2 electron configurations offer high stability efficient self‐trapped exciton (STE) emission but suffer from poor carrier transport in devices. Furthermore, most of them are incompatible host materials, leading to inefficient energy transfer inferior device performance. Herein, a Te‐based hybrid material, (PPh 3 Bu) TeCl 6 , elaborately synthesized which demonstrates strong absorption band beyond 400 nm bright orange peaked at 605 nm, photoluminescence quantum yield (PLQY) 24% lifetime 6.5 µs. Solution‐processed LEDs neat as an emitter exhibit dual emissions, achieving current efficiency (CE) 0.67 cd A −1 external (EQE) 0.34%. Inspiritingly, once blended serve light‐emitting layer, the CE EQE dramatically increased 8.1 4.3%, respectively. Notably, more than twice that SbCl 5 despite its PLQY being only one‐third thus highlighting much superior electroluminescence due facile materials. Anyway, this work pioneers use for

Organic–inorganic hybrid manganese halides (OIMnHs) have attracted significant attention in the field of optoelectronics due to their outstanding optical properties and low toxicity. However, development crystalline compounds with scintillating high light yield remains a challenge. In this study, simple solution method was employed successfully synthesize new zero-dimensional (0-D) scintillation crystal, (C13H25N)2[MnBr4] (C13H25N = trimethyladamantan-1-aminium). The introduction bulky rigid organic cations not only spatially isolates [MnBr4]2− tetrahedrons but also effectively expands Mn···Mn distance, thereby suppressing concentration quenching self-absorption effects. This structural design achieves photoluminescence quantum about 63.8% at room temperature remarkable 44,300 photons MeV−1. After multiple irradiation cycles, material retains its stable radiative characteristics. work highlights key role cation engineering improving luminescence efficiency performance provides ideas for designing efficient nontoxic OIMnH-based scintillators.
