Abstract
We investigated the elemental composition of different layers of polymeric light-emitting diode (pLED) model structures. Of special concern have been poly-(3,4-ethylenedioxythiophene) (PEDOT)/polystyrenesulfonate (PSS) and poly-phenylenevinylene (PPV) films, which are used widely in pLEDs. We found halogen compounds as impurities: bromine in the PEDOT/PSS and chlorine in the PPV layer. It is argued that the presence of halogen containing compounds could be an important reason for the degradation of pLEDs.
