| Abstract: | By employing cesium carbonate doped tris-(8-hydroxyquinoline) aluminum/MoO3 as the effective charge generation layer(CGL),high efficiency two-unit series connected tandem organic light-emitting diodes were fabricated.It is found the performance of the two-unit tandem devices can be controlled by the thickness of the MoO3 layer.The 30 nm-thick MoO3 CGL tandem device exhibits the best device performance with the current efficiency of 14.5 cd/A,which is above 2.0 times than that of the control device over a wi... |
