| 中文摘要 | in this work, organic electroluminescent (el) devices with double light-emitting layers (emls) having stepwise energy levels were designed to improve the el performance of a red-light-emitting platinum(ii) schiff base complex. a series of devices with single or double eml(s) were fabricated and characterized. compared with single-eml devices, double-eml devices showed improved el efficiency and brightness, attributed to better balance in carriers. in addition, the stepwise distribution in energy levels of host materials is instrumental in broadening the recombination zone, thus delaying the roll-off of el efficiency. the highest el current efficiency and power efficiency of 17.36 cd/a and 14.73 lm/w, respectively, were achieved with the optimized double-eml devices. at high brightness of 1000 cd/m(2), el efficiency as high as 8.89 cd/a was retained.
