AbstractMn2+ ions doped CsPbCl3 perovskite nanocrystals (NCs) exhibit superiority of spin‐associated optical and electrical properties. However, precisely controlling the doping concentration, doping location, and the mono‐distribution of Mn2+ ions in the large‐micro‐size CsPbCl3 perovskite host is a formidable challenge. Here, the micro size CsPbCl3 perovskite crystals (MCs) are reported with uniform Mn2+ ions doping by self‐assembly of Mn2+ ions doped CsPbCl3 perovskite NCs. The electron–phonon coupling strength is enhanced in the perovskite self‐assembled CsPbCl3 MCs, which remarkably accelerates the PL decay of Mn2+ ions in room temperature. Furthermore, the phonon‐involved PL emission splits to two peaks at low temperature of 80 K, due to the phonon emission and absorption‐induced energy exchange for exciton recombination in Mn2+ ions. These findings not only demonstrate a novel material system but also introduce a new theoretical framework for phonon‐modulated PL manipulation in Mn2+‐doped perovskite materials.
