采用直接法制备了Eu 3+（Tb 3+）掺杂的正硅酸乙酯（TEOS）和苯基硅（Phen-Si）共缩聚物，并对其发光性能进行了研究。在杂化薄膜中，镧系离子可以被锚定的邻菲咯啉敏化。在配体吸收波长（272 nm）处的激发导致镧系离子的强发射，即Eu 3 + D-5（0）-F-7（J）（J=0，1，2，3，4）发射线和Tb 3 + D-5（4）-F-7（J）（J = 6，5，4，3），这是由于从配体到镧系离子的能量转移。(C)2002 Elsevier Science B. V.保留所有权利。
Novel hybrid thin films covalently doped with Eu3+ (Tb3+) have been prepared via direct routes involving co-condensation of tetraethoxysilane and phen-Si in the presence of Eu3+ (Tb3+) by spin-casting and their luminescence properties have been investigated in detail. Lanthanide ions can be sensitized by anchored phenanthroline in hybrid thin films. Excitation at the ligand absorption wavelength (272 nm) resulted in the strong emission of the lanthanide ions i.e. Eu3+ D-5(0)-F-7(J) (J=0, 1, 2, 3, 4) emission lines and Tb3+ D-5(4)-F-7(J) (J = 6, 5, 4, 3) due to the energy transfer from the ligands to the lanthanide ions.
