Structured Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) Thin Films as a Light Out coupling System for Organic Light-Emitting Diodes |
| 초록 |
Conventional organic light-emitting diodes (OLEDs) suffer from poor light extraction because of the total internal reflection at the waveguided interfaces. Although the use of phosphorescent emitter materials enables for a nearly 100 % of internal quantum efficiency of OLEDs, a large number of photons are still trapped inside the device. Therefore, the development of efficient light outcoupling structures is of great necessity to achieve high efficiency OLEDs. In this study, an intentionally structured PEDOT:PSS thin films as a hole transport layer are developed for an internal light outcoupling system for OLEDs. We investigate the effect of different surface forms of PEDOT:PSS layers on the performance of OLEDs with the rough PEDOT:PSS layers. |
