摘要：

Visible red-orange poly(3-alkylthiophene) and blue poly(alkylfluorene) electroluminescent diodes have been successfully fabricated and the emission characteristics of the diode have been discussed. The electroluminescent diodes consist of thin polymer films sandwiched by ITO and Mg alloy electrodes. The dependence of emission intensity on alkyl-side-chain shows that the longer the alkyl-side-chain length is, the stronger the emission intensity of poly(3-alkylthiophene) diode is. The diode emits red-orange light having a broad band peaked at 640 nm, which correspond to the band gap of the poly(3-alkylthiophene). Novel temperature dependence of electroluminescence intensity has also been discussed. Blue emission centered at 470 nm have also been observed in poly(alkylfluorene) diode. Band diagrams of the electroluminescent diodes have also been discussed.
