A poly[2-methoxy-5-(2′-ethylhexyloxy)-1,4-phenylene vinylene](MEH-PPV) light-emitting diode was coated with passivation layers in order to improve the longevity of conjugated polymer-based diodes. High-density polyethylene (HDPE), which is an insulator, was used as the passivation material in combination with a metal layer to minimize oxygen and water diffusion into the polymer light-emitting diodes. The simplicity of the HDPE(1 μm)/Al–Li(120 nm)/HDPE(1 μm) structure, which was successively thermal coated on the diode, was demonstrated. The longevity of this simple structure was dramatically enhanced after exposure to atmospheric oxygen and moisture.
