Abstract
A device comprising an organic light emitting layer may be optically pumped to create excited states within the layer. When an electric field is applied across the layer, the excited states may dissociate into geminate polaron pairs within the organic layer. The dissociated states may change back to excitons when the electric field is rapidly reduced or removed. The organic light emitting layer may be optically pumped by an adjacent OLED, allowing for an electrically-driven device.
