Abstract
Organic thin film electroluminescent(EL) cells were fabricated. Their output characteristics and luminance versus voltage characteristics were measured with different work function metal electrodes. The EL structure was Indium-Tin-Oxide(ITO)/hole transport layer/emission layer(electron transport layer)/metal electrode. PMMA+TPD(0.5 wt%), MC homopolymer+TPD(0.005 wt%) and (MC/MMA) copolymer+TPD(0.005 wt%) were used as hole transport layer. Ca, Mg, Mg:Ag(10:l) and Al were used as metal electrode. I-V output showed exponential feature, and the threshold voltage of 5 volts and the luminance of over 700
유기 박막 electoluminescent(EL) 소자를 제작하여 전극의 일함수에 따른 출력휘도의 의존성과 휘도-전압 특성을 측정하였다. 제작된 소자의 구조는 Indium-Tin-Oxide(ITO)/정공수송층/발광층(전자수송층)/금속전극이며, 정공수송층으로는 PMMA+TPD(0.5wt%)와 측쇄 액정 고분자 메트릭스인 MC homopolymer+TPD(0.005wt%)와 (MC/MMA)copolymer+TPD(0.005wt%)을 사용하였으며, 발광층은
