Solution-phase electroluminescence.
We report emissive devices exhibiting electroluminescence in the solution phase. The principle operating mechanism for these devices--direct electronic carrier injection from the electrodes into the carrier bands of the dissolved polymer--resembles that of a conventional solid-state organic light-emitting diode and is distinct from the solvent-mediated electrochemical devices recently reported by Chang et al.
