Synthesis and characterization of PPV-based light-emitting copolymer with alkylsilylphenyloxy pendant group for light-emitting diode applications
A novel light-emitting copolymer with high brightness and luminance efficiency was synthesized using the Gilch polymerization method, and its electro-optical properties were investigated. A polymer light-emitting diode (PLED) was fabricated in ITO/PEDOT/light-emitting copolymer/Ca/Al configuration. The turn-on voltage of the PLED was about 5.0 V with maximum brightness and luminance efficiency up to 1420 cd/m(2) at 16.2 V and 0.5 cd/A at 6.8 V, respectively. (c) 2006 Elsevier B.V.
