Mn(II)-based organic–inorganic hybrid metal halides have garnered considerable attention for their potential use in X-ray imaging due to cost-effective solution processability and remarkable radioluminescence efficiency. However, achieving a photoluminescence quantum yield (PLQY) close 100% across all compositions containing Cl–, Br–, I– has been challenge. Here, we introduce an efficient spacer cation, BDPA+ (C15H18N+), which enables halide compounds achieve high PLQYs of 95–98%. The fluorescence efficiency is attributed the passivation effect provided by π-conjugated aromatic groups long distance between emissive centers afforded periodic bulk structures BDPA+. This effectively reduces energy transfer Mn2+ ions, resulting enhanced luminescence. Additionally, strong hydrophobic nature organic component ensures that crystals maintain stability over 2 months ambient air, making them suitable wide range applications. A representative scintillator prepared from (BDPA)2MnBr4 exhibits impressive performance with light 44,000 ph/MeV low detection limit 0.32 μGy/s, comparable those commercial LuAG:Ce (25,000 ph/MeV, 2.32 μGy/s). These findings hold great promise future development this class materials, particularly stable high-energy radiation detection.
