Highly conductive PEDOT:PSS films optimized with 1,3-dimethyl-2-imidazolidinone as transparent electrodes for Efficient ITO-free organic light-emitting diodes |
| 초록 |
In this work, we demonstrate on a highly conductive PEDOT:PSS thin films doped with 1,3-dimethyl-2-imidazolidinone (DMI), which significantly increases the conductivity of PEDOT:PSS films up to 812.1 S/cm. The conductivity of the PEDOT:PSS films mixed with DMI is further improved by the solvent post-treatment. The obtained highest conductivity of post-treated PEDOT:PSS with DMI films is 986.2 S/cm. The solvent post-treated PEDOT:PSS films are successfully adopted as transparent electrodes for white OLEDs. The maximum external quantum efficiency (EQE) of OLEDs with solvent post-treated PEDOT:PSS films is 16.2 %, which is higher than that of reference OLEDs based on PEDOT:PSS doped with EG (13.5 %). |
