Abstract
Thin film light emitting diodes based on multibilayer combinations of the conjugated polymer poly(phenylene vinylene) (PPV) and different po lyanions were fabricated via the use of a simple layer-by-layer molecu lar-level processing scheme. Molecular-level manipulation of the type and sequence of PPV bilayers used to construct the films was found to produce devices with dramatically improved luminance levels and effici encies. It was also found that device efficiency could be improved by controlling the nature of the thin film/electrode interface. (C) 1996 American Institute of Physics.
