采用真空热技术制备了用于顶发射有机电致发光器件的半透明Ba_（2-x）Ag双层阴极。本文报道了Ba（10 nm）scinAg（8 nm）结构在可见光区的光学透过率超过60%，方块电阻约为15Ω scinsq。阴极的表面和组成形态在确定光学性质中起着至关重要的作用。利用该阴极制备了顶发射有机电致发光器件。
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 15Ω∕sq in the Ba (10nm)∕Ag (8nm) 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.
