| 摘 要： | 利用紫外和荧光光谱技术研究了共轭聚合物PPE4+分别在溶液和薄膜中与纳晶CdTe间的能量传递现象。通过静电层层组装技术制备了混杂有纳晶CdTe的PPE4+薄膜发光二极管，并测试了其电致发光性质。结果表明在溶液和薄膜中共轭聚合物PPE4+与纳晶CdTe间均能发生有效的能量转移，而共轭聚合物PPE4+在能量传递过程中起到分子天线的作用。

| Abstract: | The photoinduced energy transfer process from conjugated polymer (PPE4+) to CdTe nanocrystals was found both in solutions and in thin films by a fluorescence spectroscopic technique. Films of PPE4+ blended with CdTe‐2 nanocrystals were formed by an electrostatic layer‐by‐layer assembly technique. Light emitting diodes were fabricated using CdTe‐2 as an emitter in PPE4+ host. PPE4+ works as a molecular wire in the energy transfer process from the polymer to the CdTe‐2 nanocrystals. |
