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.

不同烷基侧链长度的聚(3-烷基噻吩)发光二极管通过掺杂染料分子实现高效发光

利用含有荧光染料的聚(3-烷基噻吩)(P3AT)制备了电致发光(EL)二极管。掺有(1,2,3,4,5-五苯基-1,3-环戊二烯)(PPCP)的P3AT二极管的EL效率比未掺杂的二极管高500倍以上。从载流子约束和能带图的角度讨论了不同烷基侧链的P3AT二极管的发射增强机理。
