Due to surface plasmon resonance (SPR) effects and the ductility of the Ag layer, the IZTO-Ag-IZTO electrode exhibited a low sheet resistance of 4.99 Omega/sq. and a high transparency of 86% as well as superior flexibility despite the very thin thickness of the IZTO layer (30 nm). It was found that the transition of the Ag layer from distinct islands to a continuous film occurred at a critical thickness (similar to 14 nm). Continuity of the Ag film is very important for SPR in IZTO-Ag-IZTO electrode. The current density-voltage-luminance characteristics of flexible organic light emitting diodes (OLEDs) fabricated on IZTO-Ag-IZTO/PET were better than those of flexible OLEDs fabricated on an ITO/PET substrate due to the low sheet resistance and high work function of the IZTO.
