Abstract

Abstract: Mn 2+ dopants introduce a new emission center in semiconductor luminescent materials, endowing them promising photoluminescence (PL) properties, such as a wide color tuning range, reversible color change, reduced self‐absorption etc. Recently, rapid development of Mn 2+ doped metal halide perovskites (MHPs) promote their promising applications in displays, photovoltaics, scintillators, etc. The emission color, luminous efficiency, and energy transfer pathway of doped perovskites are affected by condition of host lattice that accommodates Mn 2+ ions. In this review, the optical properties determined by host materials with diverse geometries involving perovskite nanocrystals and perovskite derivatives is focused on, and the possible energy transfer routes in different doping systems are analyzed. An overview of recent advances of different doped systems with assigned emission channels together with the influence factors, strategies to enhance PL intensity and finally potential applications are summarized. To the end, the underlying challenges and possible solutions for further research in Mn doped perovskites are proposed. Abstract : According to the diverse geometries, perovskite materials are divided into perovskite nanocrystals with ABX3 structure and perovskite derivatives involving double, layered, and zero‐dimension perovskites. These host materials with different crystal field environment that accommodates Mn 2+ are responsible for their specific energy transfer pathway and luminescent behaviors. Finally, recent advances of different doped systems together with strategies and potential applications are summarized.
