Abstract: Cesium lead halide perovskite quantum dots (CsPbX₃, X = Cl/Br/I) exhibit outstanding optoelectronic properties, enabling their widespread applications in display technologies, photovoltaic devices, and photodetection. This study introduces an optimized synthesis and characterization protocol for CsPbX₃ quantum dots specifically designed for undergraduate education. Students employ the hot injection method to synthesize quantum dots, followed by comprehensive characterization using UV-Vis absorption spectroscopy, photoluminescence spectroscopy, ion chromatography, and inductively coupled plasma optical emission spectroscopy. The experiment systematically examines how halogen composition (X = Cl/Br/I) affects the optical properties of the quantum dots. Through this hands-on experience, students acquire practical skills in nanomaterial preparation and characterization while developing a fundamental understanding of structure-property relationships in quantum dots, particularly the critical role of halogen composition in determining optical characteristics. Furthermore, this experiment fosters innovative thinking by integrating laboratory practice with theoretical knowledge, ultimately enhancing students' problem-solving capabilities in complex scientific scenarios.
