Abstract

Electroluminescence(EL) with brightness up to is observed from organic light-emitting diodes fabricated on oxygen-treated anodes. An external magnetic field of applied parallel to the device surface can enhance the EL intensity by 10%, accompanied by a raised current efficiency. In-plane magnetization of the ferromagnetic anode is found to be the main origin of increase in the current contributable to EL, though magnetoresistance of the organic functional materials also plays a role in the EL enhancement observed in the magnetic field.
