| 为推进化学、材料专业实验教学与学科前沿研究的深度融合，本文设计了一项以碳点（Carbon dots, CDs）与硼氮氧化物（Boron Nitrogen Oxide，BNO）复合材料（CDs@BNO）的制备及表征"为主题的研究性综合实验。实验围绕纳米复合材料制备技术，采用水热法和固相煅烧法制备碳点，并通过微波法制备CDs@BNO复合材料，系统开展材料形貌、结构及发光性质表征。教学设计强调科研思维训练与创新能力培养，通过实验方案优化、参数调控及发光机理探究等环节，使学生掌握荧光光谱、透射电子显微镜、X射线衍射、X射线光电子能谱等现代分析技术。实践表明，该综合实验通过将前沿科研成果转化为教学项目，能够有效提升了学生的材料设计能力、仪器操作水平及数据分析技能，同时通过固态发光淬灭问题的探索式研究，培养了学生解决复杂科学问题的创新思维，为新型功能材料相关课程的教学改革提供了有益借鉴。 |
| 英文摘要: |
| To promote the in-depth integration of experimental teaching in chemistry and materials with cutting-edge disciplinary research, this study designed a comprehensive investigative experiment centered on the "Preparation and Characterization of Carbon Dots (CDs) and Boron Nitrogen Oxide (BNO) Composite Material (CDs@BNO)". The experiment focused on nanocomposite preparation techniques, employing hydrothermal or solid-phase calcination method for CDs and microwave-assisted synthesis for CDs@BNO composites, followed by systematic characterization of material morphology, structure, and luminescent properties. The instructional design emphasized training in scientific research thinking and cultivation of innovation capabilities. Through experimental scheme optimization, parameter adjustment, and exploration of luminescence mechanisms, students were guided to master modern analytical techniques including fluorescence spectroscopy, transmission electron microscopy, X-ray diffraction and X-ray photoelectron spectroscopy. Practical implementation demonstrated that this comprehensive experiment, by transforming frontier research achievements into pedagogical projects, effectively enhanced students" material design capabilities, instrumentation operation proficiency, and data analysis skills. Furthermore, exploratory investigations into solid-state luminescence quenching mechanisms fostered students" innovative thinking in solving complex scientific problems, providing valuable insights for educational reform in courses related to novel functional materials. |
