Abstract
The characteristics of AI203/Ag/AI203 multilayer passivaton prepared by twin target sputtering (TTS) system for organic light emitting diodes. The AI203/Ag/AI203 multilayer thin film passivation on a PET substrate had a high transmittance of 86.44 % and low water vapor transmission rate (WVTR) of 0.011 g/m2 -day due to the surface plasmon resonance (SPR) effect of Ag interlayer and effective multilayer structure for preventing the intrusion of water vapor. Using synchrotron x-ray scattering and field emission scanning electron microscope (FESEM) examinations, we investigated the growth behavior of Ag layer on the Al203 layer to explain the SPR effect of the Ag layer. This indicates that an AI203/Ag/AI203 multilayer passivation is a promising thin film passivation scheme for organic based flexible optoelectronics.
