Effect of well number on organic multiple-quantum-well electroluminescent device characteristics
Appl. Phys. Lett., Vol. 73, No.23, 7 December 1998,-0001,():
A doping technique for fabricating organic multiple-quantum-well electroluminescent (EL) Devices is demonstrated. This device consists of N,N8-Bis(3-methyphenyl)-N,N8-diphenylbenzidine used as a hole transporter, undoped tris(8-quinolinolato) aluminum (Alq) as a barrier potential or electron transporter, and Alq doped with 5,6,11,12-tetraphenylnaphthacene as a potential well and an emitter. Our experimental results suggest that the double-quantum-well EL devices show the optimum emission characteristics. The efficiency and the luminance of the device achieve 15.7lm/W and 7500 cd/m2, respectively.
