中文摘要	a new kind of luminescent organic-inorganic hybrid material (denoted hybrid i) consisting of europium 1,10-phenanthroline complexes covalently attached to a silica-based network was prepared by a sol-gel process. 1,10-phenanthroline grafted to 3-(triethoxysilyl)propyl isocyanate was used as one of the precursors for the preparation of an organic-inorganic hybrid materials. for comparison purposes, the hybrid material (denoted hybrid ii) in which phenanthroline was not grafted onto the silica backbone of the frameworks was also prepared. elemental analysis; nmr, ft-ir, uv/vis absorption, and luminescence spectroscopies, and luminescence decay analysis were used to characterize the obtained hybrid materials. it is shown that the homogeneity of hybrid i is superior to that of hybrid ii, and a higher concentration europium can be incorporated into hybrid i than hybrid ii. excitation at the ligand absorption wavelength (283 nm) resulted in the strong emission of the eu3+ d-5(0)-f-7(j) (j = 0-4) transition lines as a result of the efficient energy transfer from the ligands to the eu3+ in hybrid i. the number of water molecules coordinated to the europium ion was estimated, and the structure of the as-synthesized hybrid i was predicted on the basis of the experimental results.
