三价铽离子高分子配合物的光致发光和电致发光

FLUORESCENCE AND ELECTROLUMINESCENCEPROPERTIES OF Tb3+CONTAINING POLYMER

对接枝在高分子链上的铽离子的发光行为进行了研究．得到了其在溶液和薄膜状态下的光致发光光谱．研究发现，聚乙烯基咔唑（ＰＶＫ）对铽离子的发光有影响，氯仿溶液中对铽离子的发光起猝灭作用，而在薄膜状态下却使其发光增强了．对此现象的机理进行了初步探讨．把此种材料做成电致发光器件，可以观察到铽离子的绿色特征发光．

b3+containing polymer was synthesized. The interaction between poly(Nvinylcarbazole)(PVK) and it was studied by photoluminescence (PL) spectrum. It was found that the fluorescent intensity of Tb3+ was quenched by PVK in chloroform solution, but in film it was enhanced by PVK. A probable machanism was discussed. And green emission was observed using Tb3+ containing polymer.
