【摘要】 有机-无机杂化锰卤化物是一种理想的窄带绿光材料，但其封装的LED器件在点亮后快速衰减，导致无法应用。本文报道了一种有机-无机杂化锰卤化物（1-m PQBr）₂Mn Br₄(1-m PQ=1-甲基哌嗪，1-C₅H₁₂N₂)，并展示其封装LED的良好光输出稳定性。此外，针对发光弱的问题提出了优化的蒸发合成法和金属离子掺杂方法，其中掺杂10%Li的样品表现出最高的发光强度，与传统蒸发法相比提升了28%。研究发现，改进蒸发法提高了材料对蓝光的吸收；离子替代法改变了晶格结构，提升了发光强度。由（1-mPQBr）₂MnBr₄封装的白光LED色域覆盖范围达到106%NTSC，在10 m A的驱动电流下，光效112 lm/W。该发现为有机-无机杂化锰卤化物在高色域显示领域的应用打开了大门。更多还原

【Abstract】 Organic-inorganic hybrid manganese halides are ideal narrow-band green light materials, but their encapsulated LED devices rapidly degrade after being lit, making them unsuitable for applications. This paper reports on an organic-inorganic hybrid manganese halide,（1-mPQBr）₂MnBr₄, and demonstrates the good light output stability of its encapsulated LED. In addition, to address the issue of weak luminescence, optimized evaporation synthesis methods and metal ion doping techniques have been proposed. Among these, the sample doped with 10% Li exhibited the highest luminescence intensity, which was a 28% improvement compared to the traditional evaporation method. This study found that the improved evaporation method enhanced the material’s absorption of blue light; the ion substitution method altered the crystal structure, thereby increasing the luminescence intensity. The white light LED encapsulated by（1-mPQBr）₂MnBr₄ has a color gamut coverage of 106% NTSC, with a luminous efficacy of 112 lm/W at a drive current of 10 mA. This discovery opens the door for the application of organic-inorganic hybrid manganese halides in the field of high-color-gamut displays.更多还原
