The acrylic acid (AA) was grafted onto the PE film surface through UV photograft polymerization. With certain pH value, the grafted films were made to react with the alcohol-water solution of Eu3+ and alpha-thenoyltrifluoroacetone (TTA) or with the chloroform-water solution of Tb3+ and acetyl actone (AcAc), thus causing the preparation of the red or green fluorescent films. As compared with the corresponding Eu(TTA)3.(H2O)2 or Tb(AcAc)3.(H2O)2 solid complexes, both the excitation and emission spectra of the fluorescent films changed remarkably. It's predictable that chemical bond combination has occurred between the rare earth complexes and the macromolecular material. In addition, the IR spectra of the fluorescent films were also observed.
通过紫外光接枝聚合将丙烯酸（AA）接枝到聚乙烯（PE）薄膜表面。在特定pH值下，使接枝后的薄膜与Eu3+和α-噻吩甲酰三氟丙酮（TTA）的醇水溶液或与Tb3+和乙酰丙酮（AcAc）的氯仿水溶液反应，从而制备出红色或绿色荧光薄膜。与相应的Eu(TTA)3·(H2O)2或Tb(AcAc)3·(H2O)2固体配合物相比，荧光薄膜的激发光谱和发射光谱均发生了显著变化。可以预测，稀土配合物与高分子材料之间发生了化学键合。此外，还观察了荧光薄膜的红外光谱。
