Abstract

Two kinds of voltage-tunable-color triple layer organic light emitting diodes consisted of styryltriphenyamine SA and 8- hydroxyquinoline aluminum chalet Alq³ or laser dye DCM doped Alq³ as emission layers and oxadizole PBD as carrier confinement layer have been fabricated. They emit both from SA and Alq³ or DCM doped Alq³ and their emission color dependent on the applied voltage. The ratios of blue from SA and green or orange-red from Alq³ or Alq³:DCM increased with the increasing of applied voltage. Brightness current characteristic has been invest9iEnergy models have been assumed and the EL behaviors are explained.
