摘　　要：合成了一种含有载流子传输功能基团咔唑和噁二唑的有机铕(Ⅲ)配合物.在研究了光致发光等性能的同时,制备了结构为ITO/NPB(40 nm)/2.5%铕(Ⅲ)配合物:CBP(30 nm)/BCP(10 nm)/Alq3(30 nm)/LiF(1 nm)/Al(100 nm)的电致发光器件,器件在612 nm处有半峰宽为4 nm的高纯度的明亮红光发射,起亮电压约为6 V,在17.3 V时达到最大亮度1778 cd/m2.A novel europium （ Ⅲ ） complex containing a carbazole and an oxadiazole fragments as carriertransporting functional groups was synthesized. Besides photoluminescence and some other physical properties of it were studied, an electroluminescence device doped with the europium complex, ITO/NPB （40 nm）/ 2. 5% Eu complex ：CBP（30 nm）/BCP（ 10 nm）/Alq3 （30 nm）/LiF（ 1 nm）/Al（ 100 nm） was fabricated and measured, NPB was N, N′-di （ naphthalene-1 -yl ） -N, N′-diphenyl-benzidiue, CBP was 4,4′-his （ carbazole-9- yl）-biphenyl, BCP was 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline and Alq3 was tris （ 8-hydroxyquino-line） aluminium, respectively. The device gave pure and bright red light-emitting centered at 612 nm with the half peak bandwidth 4 nm. The turn-on voltage brightness was about 6 V and the maximum luminance brightness 1778 cd/m^2 at a driving voltage of 17.3 V.
