【摘要】以TTA为配体合成了新的共掺杂稀土配合物Tb0.5Eu0.5(TTA)3Dipy,通过与PVK的掺杂,分析了PVK和Tb0.5Eu0.5(TTA)3Dipy之间的能量传递过程,并且制备了以PVK∶Tb0.5Eu0.5(TTA)3Dipy为发光层的结构为ITO/PVK∶Tb0.5Eu0.5(TTA)3Dipy/PBD/Al的发光器件,通过改变两者之间的质量比,得到了较纯的Eu3+的红色发光。通过与PVK∶Eu(TTA)3混合体系的比较,发现Tb3+的引入,起到了能量传递桥梁的作用,提高了PVK到Eu3+的能量传递,从而抑制了PVK的发光。因此,通过引入适当的第二种金属离子,会增强另一稀土离子的发光,是作者提高稀土离子发光效率的一种有效的手段。更多还原

【Abstract】 The new complex Tb0.5Eu0.5(TTA)3Dipy was synthesized. By doping polymer PVK with Tb0.5Eu0.5(TTA)3Dipy, the EL device was fabricated with the structure of ITO/PVK∶Tb0.5Eu0.5(TTA)3Dipy/PBD/Al using PVK∶Tb0.5Eu0.5(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 Tb0.5Eu0.5(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.更多还原
