Paper Abstract

A spin-coated doped-polymer light emitting diode is studied. Blue electroluminescence decays within one hour. X-ray reflectivity analysis of the aged diode shows the formation of an interfacial layer made of the ITO semi-transparent electrode indiffused into the polymer. X-ray reflectivity stands as a powerful tool for aging studies of organic semiconducting devices.
