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.
