基于“以学生为中心”的大学本科创新训练项目设计——以核/壳/壳结构SiO_(2)@TbPO_(4)@SiO_(2)的合成与荧光性质为例

Design on the College Students Innovative Entrepreneurial Training Plan Program Based on the“Student-Centere”--A Case Study of Synthesis and Luminescence of the Core/Shell/Shell Structure SiO_(2)@TbPO_(4)@SiO_(2)

以提升学生的科学素养与创新能力为目标,通过创新训练项目设计合成了核/壳/壳结构SiO_(2)@TbPO_(4)@SiO_(2);对产物进行了扫描电镜(SEM)、透射电镜(TEM)、X射线光电子能谱(XPS)及红外光谱(IR)测试,并研究了材料的荧光性能。通过所学基础理论知识,对目标产物进行组成分析、机理讨论及性能测试,培养学生从事科研工作的能力。

In this paper,the college students'innovative entrepreneurial training plan program is designed to improve the scientific literacy and ability to innovate of undergraduate students.The core/shell/shell structured rare earth phosphate photoluminescent nanomaterials SiO_(2)@TbPO_(4)@SiO_(2)were controlled prepared in this program.The obtained products were characterized by scanning electron microscopy(SEM),transmission electron microscopy(TEM),X-ray photoelectron spectroscopy(XPS),and infrared spectroscopy(IR).Furthermore,the photoluminescence of SiO_(2)@TbPO_(4)@SiO_(2)has been investigated.Further the students'ability to engage in scientific research was developed by the composition analysis,mechanism discussion and performance testing the synthesized products.
