Abstract: A novel europium(Ⅲ) complex containing a carbazole and an oxadiazole fragments as carrier-transporting 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’-bis(carbazole-9-yl)-biphenyl, BCP was 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline and Alq3 was tris(8-hydroxyquinoline) 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/m2 at a driving voltage of 17.3 V.
