The present work reports on the fabrication of polymer light-emitting diodes by blending a small amount of poly(2-methoxy-5-(2′-ethylhexyloxy)-1,4-phenylene vinylene) (MEH-PPV) with poly(2,3-dibutoxy-1,4-phenylene vinylene) (DB-PPV). The optical spectra of the devices made of various ratios of the DB-PPV/MEH-PPV blends have shown that the inter-chain interactions of MEH-PPV chains were efficiently suppressed in the presence of DB-PPV as the host, resulting in the improvement of thermal stability and electroluminescence (EL) efficiency of the devices. The enhanced performance of the devices is attributed to the efficient Fo{combining double acute accent}rster energy transfer and charge trapping on the polymer blends of the DB-PPV/MEH-PPV host-guest system.
