Pb-free perovskite nanocrystals synthesis method and Pb-free perovskite nanocrystals synthesized thereby

摘要

The present invention relates to a method for synthesizing lead-free perovskite nanoparticles capable of controlling the size and shape of nanoparticles by raising the temperature of a reaction precursor solution in a single step, and to lead-free perovskite nanoparticles synthesized by the method, It includes the steps of forming a mixed solution by introducing a lead-free metal precursor, a surfactant, and a surface stabilizer in a non-polar solvent, and synthesizing the lead-free perovskite nanoparticles by increasing the temperature of the mixed solution.
