Abstract

We report photo- (PL), and electroluminescence (EL) realized via intrachain and interchain energy transfer in poly[9,9-(2'-octyl)fluorene-2,7-vinylene]-co-poly[2-methoxy,5-(2'-ethyl-hexyloxy)-1,4-phenylenevinylene] (PFV-co-MEH-PPV) copolymer systems. Energy transfer begins even at the device using 5 % MEH-PPV copolymer, and shows the best device performance for the 10 % MEH-PPV copolymer.
