| 摘 要： | 本文报道了一种用于堆叠结构有机电致发光器件的新的电荷生成层: LiF/Al/V2O5,采用这种电荷生成层的堆叠器件的两个发光单元互相独立,不受影响.说明在外加电场下,这种电荷生成层具有向邻近的发光单元注入电子空穴的能力.而堆叠了两个相同发光单元的器件的电流效率在相同的电流密度下约为普通单层结构的1.7倍.同时这种电荷生成层避免了溅射indium tin oxide(ITO)和金属、有机物共掺,只需要热蒸发,生长工艺简单.

| Abstract: | We report on a novel charge generation layer(CGL) of LiF/Al/V2O5 for a stacked organic light-emitting device(SOLED). The two emitting units of SOLED based on the CGL are independent as if they are individual devices. The CGL has an ability to inject electrons and holes into two adjacent emitting units. The luminance efficiency of the SOLED based the CGL is 1.7 times of the control device at the same current density. Moreover, the novel CGL can be prepared only with thermal evaporation without sputtering TIO or co-evaporation of metal and organic material during device fabrication, thus making the device processing. |
