摘要：Colloidal lead halide perovskites nanocrystals, also known as quantum dots, have been intensively studied as promising optoelectronic materials and have attracted widespread attention due to their unique optical versatility, high photoluminescence quantum yield and convenient synthesis. Among them, the potential of all-inorganic halide caesium lead perovskite (CsPbX 3 , X = Cl, Br, I) is particularly prominent. In this work, by adjusting the experimental parameters, including precursor preservation condition, reaction temperature and the isolation/purification process, CsPbBr 3 quantum dots with uniform size, neat arrangement, narrow full width at half maxima and excellent luminescent properties have been successfully prepared, which lays a good foundation for its potential application in practical optoelectronic devices.
