摘要：

Polymer/nanoparticle composites show the enhanced optical and electronic properties. In this study, poly(2-methoxy-5-ethylhexyloxy-1,4-phenylene vinylene) (MEH-PPV)/rutile-TiO2. composite films were made with various sizes from 7 to 23 nm and their electroluminescent characteristics were investigated, where the device structure of indium tin oxide (ITO)/nanoparticle dispersed MEH-PPV/Alq(3)/Li:Al was used. It was found that the luminance efficiency increases from 7 to 23 nm. Tn comparison with single polymer device, the brightness and luminescence efficiency of multi-layer device improved five times under 9 V de. (C) 2000 Elsevier Science S.A. All rights reserved.
