摘要：
We report a significant enhancement of the electron injection by inserting a 1-nm-thick Ba electron injection layer between n-Si cathode and tris (8-hydroxyquinoline) aluminum (Alq(3)) in inverted top-emitting OLEDs. The turn-on voltages of the OLEDs decreased dramatically from 20 V to 9 V and the efficiencies were significantly enhanced by a factor of 13 with Ba electron injection layer, which played a role in reducing the energy barrier for the electron injection, leading to the reduction of the turn-on voltages and the enhancement of the efficiencies of the n-Si based inverted top-emitting OLEDs.
