Organic Light Emitting Diode Using Mg Doped Organic Acceptor Involved in Electron Inj ection

Abstract
One new-typed organic light·emitting diode using an Mg doped organic electron acceptor(PTCDA)as electron injeetion layer and Ag as cathode was demonstrated.Compared with the traditional Mg：Ag cathode，PTCDA：Mg/Ag provid· ed nearly the same electron injection to Alq3. But due to the better reflection of Ag to the visible light over Mg：Ag cathode，corresponding efficiency was enhanced about 40％.In the amorphous film of PTCDA：Mg，PTCDA and Mg were considered to form a complex via a weak coupling. -
