Abstract

A technique for inducing white-light emission from organic multiheterostructures is proposed. The configuration of organic multiheterostructure white-light emitting diodes is ITO/TPD(50 nm)/BePP₂(5 nm)/TPD(4 nm)/BePP₂:rubrene(5 nm)/TPD(4 nm)/Alq₃(10 nm)/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 9 V. The maximum brightness and luminous efficiency of this device are 4000 cd/m² (at 17 V) and 0.4 Im/W, respectively.
