• Using poly(9-vinylcarbazole)(PVCz) as a host material for tris(2-phenylpyridine)iridium (Ir(ppy)_3) guest emitter, double-layer and triple-layer organic light-emitting devices were fabricated. Tris(8-hydroxyquinolino)aluminum (Alq_3) and 1, 3-bis[(4-tert-butylphenyl)-1, 3, 4-oxadiazolyl]phenylene (OXD-7) were used for electron-transporting layers. The insertion of 2, 9-dimethyl-4, 7-diphenyl-1, 10-phenanthroline (BCP) as a hole-blocking layer was also tested. The double-layer device composed of PVCz doped with 6.8 wt% Ir(ppy)_3 and OXD-7 gave the highest external quantum efficiency of 7.5% and power luminous efficiency of 5.8 lm/W at the luminance of 106 cd/m^2 (current density of 0.40 mA/cm^2 and drive voltage of 14.5V).
