结合新型生态农业应用功能材料和光学农业背景下化学相关专业的特点,开设“氮化物荧光粉Sr2Si5N8∶Eu2+与纤维素复合农用转光材料制备与表征”研究性综合实验项目,通过实验原理阐述、研究思路和方法的确立、材料制备、测试表征、数据处理等环节,使学生充分掌握专业中与化学相关的多门课程内涉及的光学材料发光过程、纤维素溶解、复合材料制备、光谱表征及分析、力学性能分析等关键知识点。实践表明,该实验项目选题针对性强,有助于提高学生的综合实验技能,有利于培养学生的基本科研素养,从而达到提高教育和教学质量的目的。
Combining with the characteristics of new chemical agriculture-related functional materials and chemistry-related professions under the background of optical agriculture, the project “Synthesis and Characterization of Nitride Phosphors Sr2Si5N8: Eu2 + and Cellulose Composite Agricultural Light-converting Materials” was established. Through the experimental principle Elaborated, the establishment of research ideas and methods, material preparation, test characterization, data processing and other aspects, to enable students to fully grasp the major courses of chemistry related to the professional light-emitting materials involved in the process of light, cellulose dissolution, composite preparation, spectroscopy Characterization and analysis, mechanical performance analysis and other key knowledge points. Practice shows that the experimental topic selection is targeted, helping to improve students ’comprehensive experimental skills, is conducive to cultivating students’ basic scientific literacy, so as to achieve the goal of improving education and teaching quality.
