Efficiency improvement of organic light-emitting diodes with pentacene as the buffer layer on ITO
首发时间:2007-11-20
Abstract:We report a study of Alq3-based organic light-emitting diodes (OLEDs) with a pentacene film deposited on indium tin oxide (ITO) as the buffer layer. The device with 1.0 nm pentacene layer shows the most efficient one as compared with the optimal standard device without a pentacene layer. The current and power efficiency are increased from 3.91 cd/A and 2.22 lm/w to 4.54 cd/A and 2.84 lm/w, respectively, and the luminance is also improved by 32%.

并五苯作为ITO的缓冲层对有机电致发光二极管发光效率的改善
摘要:我们报道了并五苯作为作为ITO的缓冲层对有机电致发光二极管性能的影响,与优化的常规器件相比,1纳米厚的并五苯对器件性能具有最佳的贡献,发光电流效率和功率效率分别从原来的3.91 cd/A和2.22 lm/w提高到4.54 cd/A和2.84 lm/w,亮度则增加了32%。
