中文摘要：

合成了一类新型稀土配合物TbY（o-MOBA）6（phen）2·2HeO，将其掺杂到导电聚合物聚乙稀咔唑（PVK）中获得了纯正、明亮的绿光发射。用这种掺杂体系分别制作了2类器件：1）ITO／PVK：TbY（o-MOBA）6（phen）e·2H2O／LiF／Al;2）ITO／PVK〈：TbY（o-MOBA）6（phen）2·2H2O／BCP／A1Q／LiF／A1。器件1的起亮电压为13V，在21V时最大亮度为18．2cd／m^2；结构优化的器件2，在23V时最大亮度可达124．5cd／m^2。将这种材料的发光性能与另一种稀土配合物Tb（o-MOBA）3phen·H2O相比较，并分别讨论了其光致发光（PL）和电致发光（EL）机理。

英文摘要：

A new kind of rare earth（RE） complex TbY（o-MOBA）6 （phen）2 · 2 H2O was synthesized,which was used as an emitting material in electroluminescence. The materiai was doped into poly N- vinylcarbazole（PVK） as the emitting layer,and two kinds of devices were fabricated with the structures： 1 ） ITO/PVK .. RE complex/LiF/A1; 2 ） ITO/PVK： RE complex/ BCP/A1Q/LiF/A1. The turn on voltage of device 1 is 13 V and the device has the highest brightness of 18.2 cd/mz at 21 V. Compared with the other kind of terbium complex Tb（o-MOBA）3 phen · H2O, photoiuminescence（PL） and electroluminescence（EL） mechanisms of this material were discussed. Bright green emission was obtained from the optimized multi-layer device 2,and the highest EL brightness reached 124.5 cd/m^2 at the voltage of 23 V.
