Solvothermal synthesis of Mn-doped CsPbCl₃ perovskite nanocrystals with tunable morphology and their size-dependent optical properties.

ABSTRACT: Doping metal ions in inorganic halide perovskite (CsPbX₃, X = Cl, Br, I) nanocrystals (NCs) endows the NCs with unique optical characteristics, and has thus attracted immense attention. However, controllable synthesis of high-quality doped perovskite NCs with tunable morphology still remains challenging. Here, we report a facile, effective and unified strategy for the controllable synthesis of Mn-doped CsPbCl₃ quantum dots (QDs) and nanoplatelets (NPLs) via a single-step solvothermal method. The incorporation of Mn²⁺ into CsPbCl₃ NCs introduces new broad photoluminescence (PL) emission from Mn²⁺ while maintaining the structure of host CsPbCl₃ NCs nearly intact. The PL intensity, emission peak position and size of the
