It is found that the applied electric field changes both the energy levels and the electronic wavefunctions in electroluminescent polymers: applied field induces two localized electronic states near the midgap, and also polarizes these localized electronic states, so the polarization occurs at weak or moderate fields. In addition, the strong field will dissociate a bipolaron exciton and lead to photoluminescence quenching.展开更多
