Abstract
Description
본 발명은 어떻게 작동되는가에 대하여 이론에 의해 한정되지는 않지만, 전압이 증가될 때 Alq3 방사의 증가에 대한 설명은 Alq3와 PtOEP에 대한 포토루미네센스의 상이한 수명과 연관된다. Alq3에 대한 상기 PL 수명은 고체 상태와 용액 상태 모두에서 약 13 나노초이지만, PtOEP의 PL 수명은 매질에 의존하여 약 10에서 100 마이크로초까지 다양하다. 만약 PtOEP-도핑된 장치에 인가된 전압이 낮게 유지되면, PtOEP에 전이된 엑시톤들의 수는 여기된 PtOEP 분자들이 Alq3 여기 생성율에 비례하여 충분한 비율로 이완될 수 있도록 충분히 작아지며, 그 결과 Alq3로부터 에너지 전달을 위한 충분한 도판트 분자들이 존재하게 된다. 전압이 증가함에 따라, 상기 유용한 PtOEP 도판트 분자들이 포화되며 그리고 상기 엑시톤들이 Alq3에서 생성되는 비율을 유지하도록 충분히 빠르게 이완될 수는 없다. 이런 높은 전압 영역에서, 상기 엑시톤 에너지들이 PtOEP 분자들에게 전달되기 전에 방사적 방사에 의해 몇몇 Alq3 엑시톤들이 이완된다. 6 mol% PtOEP에서, 충분한 도판트는 모든 엑시톤들을 트랩하기 위해 존재하지만, 더 높은 도핑 레벨은 전체적인 효율을 감소시킨다.
여기서, X가 C일 때 a는 1이고; X가 V일 때 a는 0이다; c가 1일 때 b는 0이다; 그리고 b가 1일 때 c는 0이다.
