Abstract

The new complex Tb0.5 Eu0.5 (TTA)3Dipy was synthesized. By doping polymer PVK with Tb0.5 Eu0.5 (TTA)3Dipy, the EL device was fabricated with the structure of ITO/PVK: Tb0.5 Eu0.5 (TTA)3Dipy/PBD/Al using PVK: Tb0.5 Eu0.5 (TTA)3Dipy as the emitting layer. Compared with the blend PVK: Eu(TTA)3, the Tb3+ acts as an energy transfer bridge, which enhances the energy transfer efficiency between PVK and Tb0.5 Eu0.5 (TTA)3Dipy. As a result, the emission of Eu3+ is enhanced with the quenching of the emission of PVK. The process of energy transfer was studied.

摘要

合成了新型配合物Tb0.5 Eu0.5 (TTA)3Dipy。通过用Tb0.5 Eu0.5 (TTA)3Dipy掺杂聚合物PVK，以PVK: Tb0.5 Eu0.5 (TTA)3Dipy作为发光层，制备了结构为ITO/PVK: Tb0.5 Eu0.5 (TTA)3Dipy/PBD/Al的电致发光器件。与共混物PVK: Eu(TTA)3相比，Tb3+充当能量转移桥，提高了PVK与Tb0.5 Eu0.5 (TTA)3Dipy之间的能量转移效率。结果，随着PVK发射的猝灭，Eu3+的发射增强。研究了能量转移过程。
