Paper Abstract

An organic quantum-well structure electroluminescent device is fabricated by a doping method. The quantum-well structure consists of (formula available in paper) as potential well and emitter, undoped NPB as a barrier potential. Compared with a conventional doping structure device, both the maximum brightness and electroluminescent (EL) efficiency of the device are enhanced, reaching 40 000 cd/m2 and 5.6 cd/A, respectively. Especially, with the increase of the drive voltage, the EL efficiency (cd/A), after reaching its maximum, declines very slowly, almost independent of the drive voltage in a wide range from 5V to 13V. The characteristic may be useful in improving the lifetime of the device.
