Abstract

Acetone, regarded as a poor solvent for perovskite materials, was found to be suitable for synthesis of the perfluoroalkyl-based two-dimensional (2D) perovskite (C3F7CH2NH3)2PbBr4. One-step synthesis gave this material as a pure phase exhibiting quantum- and dielectric-confinement effects. However, N,N-dimethylformamide (DMF), a traditional perovskite solvent, did not produce these properties.
