Abstract

It was proposed that recombination electroluminescence (EL) observable without charge injection from electrodes, when the concept of field-assisted bipolar charge generation in organic semiconductors is used. Double-insulated organic EL devices working at ac driving were also presented. When the devices were driven with ac voltage, bright surface emission was observed. Charge recombination EL is observed without charge injection from external electrodes in double-insulated organic EL devices.
