P‐183: Improved Device Stability for Solution‐Processed Green Phosphorescent OLEDs via Interface Mixing Effect

Abstract

We have improved the stability of OLEDs via adjusting the charge balance through partial interface mixing using a linear polymer (LPHTL) which has relatively higher hole mobility than cross-linkable HTL (XHTL). Then we analyzed this phenomenon through hole only device (HOD) and impedance spectroscopy (IS).
