无机/有机稀土配合物杂化发光材料研究进展

近年来材料的发展趋势是功能互补,性能优化。稀土配合物发光强度大、单色性好,缺点是光稳定性和热稳定性较差,因此须将其掺入一定基质中,这样所得到的有机 /无机杂化发光材料,兼备了有机、无机材料的优点。根据杂化材料中稀土配合物与基质之间作用力不同,可分为第一类杂化材料(两相间以弱键如氢键等结合)和第二类杂化材料(两相间以强键如共价键等结合)。对这两类杂化材料近年来国内外的研究情况作了综合评述,并展望了其发展趋势。

Development of Study on Inorganic/Organic Hybrid Luminescent Materials Doped with Rare Earth Complex

Recently, the developing direction of materials is the functional complementarity and the property optimization.The rare earth complexes have highly luminescent properties and good chromatic purity, but they are unstable and lack the desired mechanical properties to be directly used as luminescent sources. These problems are expected to be solved by doping the complexes into suitable solid matrices. The resulting (inorganic/)organic hybrid luminescent materials combine the respective characteristics of organic and inorganic parts.According to the interactions between the rare earth complexes and the matrices, the hybrid materials include Class Ⅰ(the interactions are weak, typically hydrogen bonds or Van der Waals forces) and Class Ⅱ(the organic ligand is covalently linked to the silica framework).We briefly describe the preparation methods and give a review on the developments for the two classes hybrid luminescent materials. The developing trend for inorganic/organic hybrid materials doped with rare earth complex is also prospected.
