A technique for inducing white-light emission from organic multiheterostructures is proposed. The configuration of organic multiheterostructure white-light emitting diodes is ITO/TPD(5nm)/BePP2(5nm)/TPD(4nm)/BePP2 :rubrene(5nm)/TPD(4nm)/Alq3(10nm)/Al. Triphenyldiamine derivative (TPD) is used as a hole-transporting layer and the potential barrier layers. Blue fluorescent phenylpyridine beryllium (BePP2), orange fluorescent rubrene, and green fluorescent aluminum complex (Alq3) are used as three primary colors. BePP2 and BePP2 doped with rubrene act as the potential wells sandwiched between TPD barrier layers, in which excitons are confined. Alq3 is used as an electron-transporting green-color emitter. The white-light emission spectrum covers a wide range of the visible region, and the Commission Internationale de l'Eclairage coordinates of the emitted light are (0.32, 0.38) at 9V. The maximum brightness and luminous efficiency of this device are 4000 cd/m2 (at 17V) and 0.4lm/W, respectively.
