摘　　要：文章用一系列含氮杂菲类中性配体的铕配合物Eu(DBM)3pyzphen、Eu(DBM)3dpmq、Eu(DBM)3dppz和Eu(DBM)3dptp制作了有机EL器件,研究了它们的电学特性。采用的器件结构为ITO/TPD/CBP:Eu(DBM)3L/BCP/Alq3/LiF/Al(L=pyzphen、dpmq、dppz和dptp),其中基于Eu(DBM)3pyzphen的器件获得了992cd/m2的最大亮度和2.9cd/A的最大效率。在此基础上分析了第二配体对器件性能的影响。Several europium complexes such as Eu（DBM）3pyzphen,Eu（DBM）3dpmq,Eu（DBM）3dppz and Eu（DBM）3dptp were prepared and their EL performances were studied respectively.The used device structure in this paper was ITO/TPD/CBP：Eu（DBM）3L/BCP/Alq3/LiF/Al（L=pyzphen,dpmq,dppz and dptp）.A maximum current effciency of 2.9 cd/A and a maximum brightness of 992 cd/m2 were obtained from a 11wt% Eu（DBM）3pyzphen doped device.Effects of the second ligand upon EL performances were discussed in brief.
