| 英文摘要 | Kinds of organic-inorganic hybrid materials consisting of lanthanide (er3+, eu3+, and tb3+) complexes covalently bonded to a silica-based network have been obtained by a sol-gel approach. a new versatile compound containing terpyridine has been synthesized by 4'-p-aminophenyl-2,2':6',2 ''-terpyridine and 3-(triethoxysilyl)propyl isocyanate, which is used as the a ligand of lanthanide ions and also the siloxane network precursor. the obtained hybrid materials were characterized by ft-ir, tga, dsc, near-infrared, and visible spectrofluorometer, as well as decay analysis. for the hybrid-er and hybrid-eu, excitation at the ligand absorption wavelength resulted in the typical near-ir luminescence (centered at around 1.54 mu m) resulting from the i-4(13/2)-i-4(15/2) transition of er3+ ions and strong visible region emission of the eu3+ ions (d-5(0)-f-7(j)), which contributed to the efficient energy transfer from the ligands to the lanthanide ions. however, we have not found strong emission for the hybrid-tb. this indicated that the energy transfer did not take place in this system. a model of indirect excitation mechanism to explain the phenomenon was also suggested.
