Doping impurity ions into semiconductor luminescent materials offers a unique pathway for inducing new emission centers and enabling photoluminescence (PL) tuning. Among various luminescence materials, doping Mn2+ into metal halide perovskites becomes a hot topic since Mn2+ ions demonstrate an energy transfer route from host to dopants, resulting in interesting photophysical properties. This review aims to discuss the PL properties of Mn2+ ions in halide perovskites nanocrystals or bulk crystals with different structural dimensions and local environments (MnX42– tetrahedron, MnX62– octahedron, or shortest Mn─Mn distance). In this regard, the effects of Mn2+ doping on the PL properties and their modifications are summarized. Variable ion exchange dynamics, increased emission intensity, and enhanced stability induced by Mn2+ doping are analyzed. These results also provide beneficial insights into applications of the doped luminescent halide perovskites. Finally, the present challenges in Mn2+‐doped luminescent halide perovskites are elaborated.

Mn2 +掺杂的金属卤化物钙钛矿：结构，光致发光和应用
将杂质离子掺杂到半导体发光材料中，为诱导新的发射中心并实现光致发光（PL）调谐提供了独特的途径。在各种发光材料中，将Mn 2+掺杂到金属卤化物钙钛矿中成为热门话题，因为Mn 2+离子显示出从主体到掺杂剂的能量转移途径，从而产生了有趣的光物理性质。本文旨在探讨具有不同结构尺寸和局部环境（MnX 4 2 –四面体，MnX 6 2 –八面体或最短的Mn-Mn距离）的卤化物钙钛矿纳米晶体或块状晶体中Mn 2+离子的PL特性。在这方面，Mn 2+的影响总结了PL特性的掺杂及其修饰。分析了由Mn 2+掺杂引起的可变离子交换动力学，增加的发射强度和增强的稳定性。这些结果也为掺杂发光卤化物钙钛矿的应用提供了有益的见识。最后，阐述了Mn 2+掺杂的发光卤化物钙钛矿中的当前挑战。
