摘要：

A complex with Eu3+ as the luminescent center, 2-thiophenecarbonyl trifluoroacetone (TTA) as the first ligand and o-phenanthroline (Phen) as the co-ligand was designed and synthesized. The complex was then dispersed into polyvinyl alcohol (PVA) to form the EuxTb1-x(TTA)(3)phen/PVA composite. The structure and reaction processes of the composites were analyzed by FE-SEM and XRD, and the optical properties of EuxTb1-x(TTA)(3)phen complexes with different contents were analyzed by fluorescence spectroscopy.
