Manganese halides are emerging as promising alternatives to traditional inorganic phosphors and X-ray scintillators due their low toxicity, high attenuation coefficients, light yield, cost-effective solution-processability. We synthesized a novel manganese chloride, (4CTP)2MnCl4 (4CTP = (4-chlorobenzyl)triphenylphosphonium), via solvent volatilization. The crystal exhibits narrow-band (∼48 nm) green emission at 516 nm under ultraviolet or blue excitation, attributed the Mn2+ d-d transition, with photoluminescence quantum yield (PLQY) of 95.7% nearest Mn···Mn distance 9.909 Å. A white light-emitting diode (LED) for backlight displays was fabricated using (4CTP)2MnCl4, 450 LED chip, K2SiF6: Mn4+, achieving color gamut 112.1% 20 mA. Substituting red phosphor (Sr, Ca)AlSiN3: Eu2+ produced solid-state lighting rendering index (CRI) 92.4 correlated temperature (CCT) 4097 K. also demonstrated excellent scintillation properties (a 63,400 photons/MeV). flexible (4CTP)2MnCl4@PMMA film enabled high-resolution imaging (10.4 lp/mm).
