Recently, zero-dimensional (0D) hybrid metal halides have attracted intensive attention with wide applications in solid-state lighting and display diodes. Herein, by using a facile wet-chemistry method, we prepared one new 0D hybrid antimony halide of [HMHQ] SbCl ⋅ 2H O (MHQ=2-methyl-8-hydroxyquinoline) based on the discrete [SbCl ] unit. Remarkably, the bulk crystals of [HMHQ] SbCl ⋅ 2H O exhibit strong cyan light emission with a promising photoluminescence quantum yield (PLQY) of 18.92%. Systematical studies disclose that the cyan emission is mainly derived from the radiative recombination within conjugated organic cation. Benefiting from the promising luminescent performance, this 0D antimony halide can be utilized as an excellent down-conversion light emitting luminescent material to assemble white light-emitting diodes with high color rendering index (CRI) of 90.2.
最近，零维（0D）混合金属卤化物因其在固态照明和显示二极管中的广泛应用而备受关注。在此，我们采用简便的湿化学方法，基于离散的[SbCl]单元制备了一种新型的0D混合锑卤化物[HMHQ]SbCl⋅2H₂O（MHQ = 2-甲基-8-羟基喹啉）。值得注意的是，[HMHQ]SbCl⋅2H₂O的块状晶体表现出强烈的蓝光发射，其光致发光量子产率（PLQY）高达18.92%。系统研究表明，蓝光发射主要源于共轭有机阳离子内的辐射复合。得益于其优异的发光性能，这种0D锑卤化物可作为一种出色的下转换发光材料，用于组装显色指数高达90.2的白光发光二极管。
