中文摘要： 介孔有机-无机杂化发光材料作为一种性能互补的新材料正倍受青睐，但目前的研究存在硅基主体材料发光较弱、杂化材料发光效率不高的问题，同时主客体之间敏化发光机理的认识还有待深入。本项目拟在硅基介孔杂化发光材料研究的基础上，制备具有高效发光和结构稳定的新型介孔YVO4:Eu3+主体材料，利用化学自组装技术把高性能的客体三元多核稀土配合物组装到介孔YVO4:Eu3+中，构建新型多光源钒基介孔有机-无机杂化发光材料。同时，研究主客体及组装材料的物相、结构和发光性能，揭示主客体之间的成键机理及敏化发光的能量转移机理，进而建立新型介孔杂化材料的机理模型，并以此为指导对杂化材料的各种现象做出合理解释，为新型多光源介孔杂化发光材料的研究提供理论依据。项目的成功实施将有助于深入对新型多光源钒基介孔杂化发光材料的认识，促进有机化学、无机化学、传统发光材料及新兴介孔材料的学科交叉融合，具有重要的学术意义。

英文摘要： As a kind of complementary new materials, mesoporous organic-inorganic hybrid luminescent materials are extremely popular. But the current research exists the problem of the weak luminescence of host material, the lower luminous efficiency of hybrid luminescent materials and the understanding of sensitized luminescence mechanism between host and guest material is not clear. On the basis of the results obtained so far for the mesoporous silica hybrid luminescent materials, the present project is planned to develop new mesoporous YVO4:Eu3+ host material with high luminescence efficiency and structural stability. By applying a chemical self-assembly method, high-performance ternary multi-core rare earth complexes will be assembled with mesoporous YVO4:Eu3+ host material. Multi-source vanadium-based mesoporous organic-inorganic hybrid luminescent materials will also be constructed. Simultaneously,the structure and luminescent properties of the host, guest and host-guest phases will be investigated. The bonding and the sensitized luminescence energy transfer mechanisms of the host-guest interactions will be explored for the establishment of a new mesoporous organic-inorganic hybrid luminescent materials mechanism model. The successful implementation of the project will contribute to the scientific community with deep
