Abstract
| - A simple, inexpensive method involving chemical deposition ofsilver metal onto a polymerlayer by noncatalytic chemical reduction from silver nitrate solutionis used in the fabricationof polymeric light-emitting diodes (LEDs). The method yieldedsilver films with good polymer/metal interfaces and the resulting LEDs emitted light uniformly over theentire device area,but the emission efficiencies were lower by an order of magnitudecompared to LEDs withvacuum-deposited metal electrodes. The chemical deposition of themetal film was carriedout on a lab bench in open air without any special precautions. Inaddition to its costadvantage over vacuum deposition methods, the chemical process may alsoallow fabricationof polymer LEDs on nonflat and/or large area substrates.
