초록

Multi-layer organic electroluminescent(EL) devices with Al-CsF composite as a cathode were fabricated. This device privides low driving voltage and high quantum efficiency. CsF is evaporated onto and diffuse into electron transport layer. $Alq_3$. The Fermi level of $Alq_3$ moves towards the LUMO level.
