Phonon Involved Photoluminescence of Mn²⁺ Ions Doped CsPbCl₃ Micro-Size Perovskite Assembled Crystals.

ABSTRACT: Mn²⁺ 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
