Synthesis and Optical Properties of Mn2+-Doped Amino Lead Halide Molecular Clusters Assisted by Chloride Ion
Mn2+-doped amino lead halide molecular clusters (MCs) are synthesized using amine (e.g., n-octylamine, or butylamine) as passivating ligand and MnX2 (X = Cl or Br) as the Mn2+ doping source at room temperature. Their optical properties are investigated with UV-visible absorption, photoluminescence (PL), and PL excitation spectroscopy. The Mn2+ precursor plays a vital role in the synthesis of Mn2+-doped MCs. MnCl2 seems to facilitate the incorporation of Mn. The MnCl2 doping causes electronic absorption blue shift and leads to a spin-forbidden 4T1 → 6A1 Mn d-electron emission. With the help of time-resolved PL, Fourier transform infrared, and electron paramagnetic resonance results, a model is proposed to explain the formation mechanism. We suggest that Mn2+ doping replaces Pb2+ is assisted by Cl- ions that replace Br- ions. This study demonstrates the possibility of doping MCs and has important implications in gaining new fundamental insight into the growth mechanisms of perovskite nanostructures.
