| Abstract | Electrochemically modified indium-tin oxide (ITO) surfaces were used as hole injection electrodes in organic light emitting devices. Substantial improvement in hole injection and electroluminescence efficiencies were observed in devices with the sample configuration of ITO/NPB/Alq(3)/LiF/Al. The turn-on voltage reduced from 5.3 V for device with pristine ITO to 2.8 V for device with ITO pretreated electrochemically at +2.4 V in K4P2O7 electrolyte. The current and power efficiencies at 20 mA/cm(2) were increased correspondingly from 3.0 cd/A and 0.84 lm/W to 3.4 cd/A and 1.24 lm/W. The mechanisms behind this performance enhancement were discussed. |
