AbstractPolymer light-emitting electrochemical cells (LECs) were fabricated and characterized with three block copolymers containing PEO segments as the luminescent polymers. The block copolymers are composed of PPV segments with three phenylene vinylene units and PEO segments with three ethylene oxide units. Blue-green light-emission of the LECs was demonstrated with the onset voltage lower than 3 V and EL efficiency of 0.74 cd/A at 2.8 V. The response time of the LECs is approximately 5 s. The transient response and a.c. impedance data indicate that the operating mechanism of the LECs is an electrochemical doping model. (C) 2002 Elsevier Science B.V. All rights reserved.
