반투명 Al 음극을 사용하는 고분자 발광 소자(PLED)에 대한 광조사 효과가 연구되었습니다. 발광 고분자인 폴리(p-페닐렌 비닐렌) 유도체 MDOPPV가 본 연구에 사용되었습니다. 광 조사 시, 일정한 전압에서의 방출 강도는 급격히 감소했습니다. 그러나 전계발광의 양자 효율은 일정하게 유지되었으며 이는 재결합 영역과 광산화 결함 사이의 공간적 분리를 나타냅니다. 반면, 유사한 광조사에서는 광발광의 양자 효율이 급격히 떨어졌습니다. 이는 전기발광 공정과 광발광 공정 사이의 엑시톤의 기원과 공간 분포의 차이를 통해 이해할 수 있습니다. 또한 두께가 ca. 100nm는 두께 의존성이 없으며, 이는 폴리머의 광산화가 장치 전체에 걸쳐 균일하게 진행됨을 나타냅니다.

Abstract: Photoirradiation effects on the polymer light-emitting devices (PLEDs) with a semitransparent-Al cathode have been studied. A light-emitting polymers, a poly (p-phenylene vinylene) derivative MDOPPV has been used in this study. Upon photoirradiation, the emission intensity at a constant voltage was rapidly decreased. However, the quantum efficiency of electroluminescence remained constant, indicating the spatial separation between recombination zone and photooxidized defects. On the other hand, the quantum efficiency of photoluminescence rapidly dropped upon similar photoirradation. These can be understood by taking the difference in the spatial distribution and the origin of excitons between electro- and photo-luminescence processes. It was also found that the photooxidation rate of the polymer film whose thickness is ca. 100 nm does not have thickness dependence, suggesting that the photooxidation of the polymer proceeds uniformly throughout the device.
