摘要

利用聚合物三苯基二胺衍生物(Poly-TPD)掺杂2

5-双(5-叔丁基-2-苯并恶唑基)噻吩(BBOT)作为器件发光材料

研制了基于激基复合物纯正发射的有机电致发光器件。器件的具体结构为:ITO/PEDOT∶PSS (25 nm)/ Poly-TPD∶BBOT(1∶1

80 nm)/Al(70 nm)。研究结果表明

该器件的556 nm黄绿光发射来自于发光层Poly-TPD∶BBOT形成的电致激基复合物的单一发射

而源于Poly-TPD和BBOT的本征发射全部消失。

Abstract

Exciplex emission is considered to be very important for understanding the fundamental processes of electronic excitation. Here we report a pure exciplex emission device of the binary-blend ITO/ Poly(3

4-ethylenedioxythiophene)∶poly (styrenesulfonate) (PEDOT∶PSS)/poly [-bis (4-butylphenyl)-bis(phenyl) benzidine](Poly-TPD)∶2

5-bis(5-tert-butyl-2-benzoxazolyl) thiophene (BBOT)/Al. The luminance-voltage and current density-voltage characteristics of devices were investigated

and differences between their performances were discussed. The pure exciplex electroluminescence was investigated in terms of the energy level diagram of the Poly-TPD∶BBOT device.
