新型稀土发光材料的组装

By using ion-exchange method, rare earth complex was incorporated into layered compounds and thus the assembly doped with rare earth complex was obtained and their optical-physics was studied. Rare earth complex was grafted to organic/inorganic matrix by covalent-bond, and the stability of the optical centers was improved and doping concentration was also increased in the resulting hybrids. By Si-C covalent bond rare earth complex was grafted to the transparent mesoporous thin films and the luminescent properties was also studied. This is very important for the study and developing of chemical sensors. The electroluminescent properties of Sm complex was reported for the first time. A series of novel organic/inorganic with rare earth polyhyter acids were prepared and their luminescent properties, structures and the energy transfer mechanism from LB matrix to rare earth ions were studied. By using self-assemble method the self-assemble films with rare earth was prepared and the luminescent properties for the polyoxometalte was also studied.
