摘　　要：近年来,卤化物钙钛矿作为一种新型半导体材料表现出优异的性能,让其不仅在光伏领域取得青睐,而且在光电探测、生物成像、激光和发光二极管等光电器件领域也有着不俗的表现。然而卤化物钙钛矿要实现商业化仍有许多问题需要解决,如铅的毒性,空气不稳定性以及发光效率低等。离子掺杂被认为是改善这种情况的有效途径。介绍了卤化物钙钛矿结构的演变,并简要阐述了结构维度对其发光性能的影响。随后,从二价Cu^(2+)和一价Cu^(+)离子掺杂两个方面系统的阐述了目前铜掺杂卤化物钙钛矿发光特性的研究进展,分析了铜离子影响卤化物钙钛矿性能的各种机理。最后,讨论了目前铜掺杂卤化物钙钛矿研究上的不足及未来潜在的研究方向。In recent years,halide perovskite shows excellent performance as a new type of semiconductor material,which makes it favored not only in the field of photovoltaic,but also in optoelectronic devices such as photoelectric detection,biological imaging,laser and light-emitting diodes.However,there are still many problems need to be solved in the commercialization of halide perovskite,such as lead toxicity,air instability and low luminous efficiency.Ion doping is considered to be an effective way to improve this situation.In this paper,we first introduce the evolution of halide perovskite structure,and briefly describe the effects of different dimensions on its luminescent properties.Then,the current research progress of copper-doped halide perovskite is systematically described from two aspects of divalent Cu ^(2+)and univalent Cu^(+)ion doping,and the various mechanisms of the effect of copper ion on the properties of halide perovskite are analyzed.Finally,the deficiency in the current research of copper-doped halide perovskite and the potential research directions in the future are discussed.
