摘要：将新型稀土配合物TbY(m-MBA)₆(phen)₂·2H₂O掺杂到导电聚合物PVK中改善了配合物的成膜性和导电性，作为发光层应用于有机电致发光。分别制作了器件(1)：ITO/PVK:TbY(m-MBA)₆(phen)₂·2H₂O/LiF/Al和以Alq为电子传输层的器件(2)：ITO/PVK:TbY(m-MBA)₆(phen)₂·2H₂O/Alq/LiF/Al。研究了两种器件的电致发光性能, 得到了最大效率为0.88 cd·A^-1的器件。研究了铽配合物与PVK共掺杂体系的激发光谱和光致发光谱, 发现两者之间存在着能量转移, 说明Y³⁺的存在促进了PVK到Tb³⁺的能量传递。文章就器件的发光特性和掺杂体系的能量传递进行了初步讨论。

Abstract：Rare earth complex TbY(m-MBA)₆(phen)₂·2H₂O have been synthesized, which were used as emitting materials in electroluminescence. Single-layer devices and bilayer devices with Alq as electron transmission layer have been fabricated. The electroluminescent properties of the devices were studied. The electroluminescent mechanism of the devices was proposed by measuring and analyzing the emission and the excitation spectra of the emissive layer. Y³⁺ may play the role to promote the energy transfer from ligand to Tb³⁺ and the possible energy transfer process of the device was preliminarily discussed.

Key words：Electroluminescence;Energy transfer;Exciton
