All-inorganic zero-dimensional (0D) metal halides are composed of isolated metal halide polyhedrons bridged by monovalent alkali metal ions. The unique structure gives rise to molecule-like electronic configuration and consequently highly attractive optical properties. In comparison with their three-dimensional (3D) counterparts, the 0D metal halides exhibit characteristic features such as broadband emission and long-term stability. In addition, 0D metal halides can be constructed from a diverse range of metal ions and permit high-level impurity doping, thereby offering great structural designability and spectral tunability. This Review surveys recent advances in 0D metal halides, including crystal preparation, luminescence modulation, and emerging applications.
全无机零维(0D)金属卤化物由通过单价碱金属离子桥连的孤立金属卤化物多面体组成。这种独特的结构产生了类似分子的电子构型,从而具有极具吸引力的光学性质。与三维(3D)同类物相比,0D金属卤化物表现出宽带发射和长期稳定性等特征。此外,0D金属卤化物可以由多种金属离子构建,并允许进行高水平的杂质掺杂,从而具有很大的结构可设计性和光谱可调性。本综述概述了0D金属卤化物的最新进展,包括晶体制备、发光调制和新兴应用。
