Figure 7

(a) Current density-voltage curve, (b) luminance-voltage curve, (c) current efficiency–current density curve, and (d) EL spectra of flexible OLEDs fabricated on ion-plated IWO and sputtered ITO anodes. Both samples were fabricated in the same chamber used to deposit the organic layers and metal cathode. The inset picture in (b) shows green light emission from the flexible OLED with the ion-plated IWO anode.
