摘要

The colloidal synthesis of halide perovskite quantum dots has been extensively studied due to their superior optical properties. However, synthesizing stable iodide-based perovskite quantum dots continues to pose challenges. In this work, by choosing an alternative solvent among several preferences such as dimethylformamide (DMF), dimethylsulfoxide (DMSO), and acetonitrile (ACN) as a solvent to form the precursor MAPbI3, and using an antisolvent suitable for this precursor, obtaining perovskite quantum dots with a stable MAPbI3 structure was achieved. The synthesized MAPbI3 perovskite quantum dots were found to maintain their bright red luminescence for over 8 months. The spectral properties of synthesized MAPbI3 quantum dots were investigated using electronic absorption and fluorescence spectroscopies.
