Abstract
Electroluminescent (EL) diodes utilizing poly(3-alkylthiophene) (P3AT) containing fluorescent dyes have been fabricated. It has more than 500 times higher EL efficiency in P3AT diodes doped with (1,2,3,4,5-pentaphenyl-1,3-cyclopentadiene) (PPCP) than in undoped diode. The mechanism of emission enhancement in P3AT diodes with different alkyl side chains has been discussed in terms of carrier confinement and energy band diagram.
