摘　　要：锰离子是发光材料家族中最重要的激活剂离子之一。锰离子无论是作为掺杂离子还是作为基质材料,都可以提高卤化物钙钛矿的发光性能。但是合成的驱动力不同,发光稳定性也不同;由于结合能和形成能的改变,热稳定性和环境稳定性也随之改变。锰离子的发光机理相对清晰明了。基质的激子发射和瞬态光导致晶格缺陷引起的自陷态发射也可能参与锰离子的发光机制。在这篇综述中,我们将分析不同类型结构的锰掺杂卤化物钙钛矿和锰基卤化物钙钛矿的发光机理,重点是锰离子的掺杂驱动力和掺杂策略。Mn^(2+)is one of the most important activator ions in the family of luminescent materials.Whether as doped ions or raw materials of the host,it can improve the luminescence performance of halide perovskite.However,the driving force of the synthesis has changed,as well as the luminescence stability.This is because the binding energy and formation energy have changed,along with the thermal stability and environmental stability.The luminescence mechanism of Mn^(2+)ions is relatively distinct.Exciton emission of the host and self-trapped emission(STE)caused by transient photo-induced defects may also participate in the luminescence mechanism.In this review,we will summarize the luminescence of different types of structures of Mn^(2+)doped halide perovskites or Mn^(2+)based halide perovskites,focusing on the doping driving force and doping strategy of Mn^(2+)ions.
