- Abstract
- Light-emitting devices based on environmentally stable polymer/layered silicate nanocomposite were fabricated by blending poly[2methoxy-5-(2'-ethyl-hexyloxy)-1,4-phenylene vinylene] (MEH-PPV) with organo-clay. The ratio of MEH-PPV/organo-clay was regulated from 5/1 (w/w) to 1/1 (w/w). The light-emitting device of 1/1 (w/w) blend gives us the highest quantum efficiency, 0.38 % ph/el, which is enhanced 100 times compared with the pure MEH-PPV layer device, This 2-dimensional lamellar-type nanocomposite device forms a similar electronic structure to that of commonly known quantum well devices. Thus, this method can promote to confine both the electrons and holes to enhance the recombination rate.
