Abstract: To improve the research literacy and practical skills of undergraduates in chemical engineering, chemistry, materials science, and related disciplines, we designed a comprehensive experiment involving the preparation of perovskite quantum dots through room-temperature ligand-assisted reprecipitation. This experiment encompasses the synthesis principles, preparation procedures, optical characterization, and fabrication of photoluminescent white light emitting diodes using both red-emitting CsPbBr_xI₃_-_x and green-emitting CsPbBr₃ perovskite quantum dots. Through this experiment, students will gain fundamental knowledge about this cutting-edge research field while reinforcing their understanding of inorganic chemistry and instrumental analysis. The experiment enhances students’ comprehension of solubility principles and spectral analysis techniques, develops essential laboratory skills, stimulates scientific curiosity, and cultivates problem-solving abilities，so as to lay a solid foundation for future scientific research.
