A white light-emitting organic/polymeric electroluminescent (EL) device with multilayer thin-film structure is demonstrated. The device structure of glass substrate/indium-tin oxide/poly(N- vinylcarbazole)/phenylpyridine beryllium(BePP2)/8- (quinolinolate)-aluminum (Alq) doped with 5,6,11,12- petraphenylnaphthacene/Alq/LiF/Al was employed. The turn-on voltage is as low as 2.9 V. Blue fluorescent BePP2 yellow fluorescent rubrene, and green fluorescent Alq are used as three primary colors. The Commission Internationale de l'Eclariage coordinates of the emitted light are at 10V, which is located in the white-light region. Bright white light, over 6800cd/m2, was successfully obtained at about 17V, and the maximum efficiency reaches to 1.38m/W at 8.5V.
