摘要
制备了一种基于新的电荷生成层m-MTDATA∶MoO3的叠层有机电致发光器件。叠层器件与单发光层器件相比,发光亮度和电流效率均有成倍的提高。叠层器件的最大电流效率达到了30.06 cd/A,最大亮度为83 210 cd/m2,分别约为普通器件的2倍。除此之外,叠层器件在整个电流密度范围内的电流效率都很稳定。结果表明:m-MTDATA∶MoO3可以作为高效率的叠层有机电致发光器件的电荷生成层。
A tandem organic light-emitting diode(OLED) with a new charge generation layer of m-MTDATA:MoO3 has been studied.Compare to the OLED with single electroluminescence unit,the tandem OLED shows an enhanced luminance and current efficiency by a factor of nearly 1.The maximum luminance and the maximum efficiency of tandem OLED are 83 210 cd/m2 and 30.06 cd/A,respectively.
