摘要：

Electroluminescent (EL) diodes utilizing poly(3-alkylthiophene) containing fluorescent dyes have been fabricated and their unique characteristics have been studied. The EL efficiency has been enhanced by a factor of 100 in poly(3-alkylthiophene) diodes doped with cyclopentadiene derivative compared with that in undoped poly(3-alkylthiophene) diodes. Color-variable light emission with increasing applied voltage, as well as improvement of the EL efficiency, has been observed in diodes with poly(3-alkylthiophene) containing oxadiazole derivative.
