Solution Synthesis,Photophysical Properties and Photoelectric Application of Zero-dimensional Organic-inorganic Hybrid Metal Halide

零维(0D)有机-无机杂化金属卤化物作为一种重要的功能材料,由于其优异的发光特性,在照明、显示和X射线闪烁体等领域得到了广泛的关注。在0D有机-无机杂化金属卤化物中,金属卤化物多面体阴离子被有机阳离子包围并完全孤立,形成独特的“主-客体”结构。因此,0D有机-无机杂化金属卤化物通常表现出单个金属卤化物多面体的固有特性。然而,0D有机-无机杂化金属卤化物作为一种新兴的发光材料,除了包含显著的空间限域特征,其还有可调的微观相互作用,因此不同的成分对它们的发光物理机制具有显著的影响。基于此,本文首先介绍了0D有机-无机杂化金属卤化物的溶液合成方法、晶体结构特征和发光物理机制;然后详细分析了0D有机-无机杂化金属卤化物发光物理机制的调控以及光电方面的应用;最后,对0D有机-无机杂化金属卤化物的未来应用和研究进行了总结和展望。

Zero-dimensional(0D)organic-inorganic hybrid metal halides,as an important functional material,have received widespread attention in the fields of lighting,display,and X-ray scintillator for their excellent luminescent properties.In 0D organic-inorganic hybrid metal halides,the polyhedral anions of metal halides are surrounded by organic cations and completely isolated,forming a unique“host-guest”structure.Hence,0D organic-inorganic hybrid metal halides generally exhibit the intrinsic properties of single metal-halide polyhedrons.However,0D organic-inorganic hybrid metal halides,as an emerging luminescent material,not only contain significant spatial confinement characteristics,but also have tunable micro interactions.Therefore,different components have a significant impact on their photophysical mechanism.Based on this,this review first introduces the solution synthesis methods,crystal structure characteristics,and photophysical mechanism of 0D organic-inorganic hybrid metal halides,and then analyzes in detail the regulation of the photophysical mechanism and optoelectronic applications of 0D organic-inorganic hybrid metal halides.Finally,we summarize and prospect the future applications and research of 0D organic-inorganic hybrid metal halides.
