Abstract

Using a vacuum thermal technique, semitransparent Ba/Ag bilayer cathode has been fabricated for the top-emitting organic light emitting devices. In this work, optical transparency over 60% in the visible region and low sheet resistance of about 15 Ω/sq in the Ba (10 nm)/Ag (8 nm) structure are reported. The surface and compositional morphologies of the cathode play a crucial role in determining the optical properties. Top-emitting organic light emitting device using this cathode has been fabricated and studied.
