Precursor Stoichiometry-Regulated Room-Temperature Synthesis and Surface Reconstruction of Highly Emissive CsPbI3 Perovskite Nanoplatelets
Room-temperature synthesis of uniform CsPbI3 nanoplatelets (NPLs) is hindered by their fast crystallization and instability. Here, we demonstrate a ligand-assisted reprecipitation (LARP) approach under ambient conditions in which the Cs/Pb precursor stoichiometry is used to regulate the room-temperature crystallizati...
