The operating process of light-emitting electrochemical cells (LECs) is investigated by operando spectroscopy in the visible and near-infrared regions. We have succeeded in observing the dynamical processes of hole and electron carriers during recombination processes of LECs, by which the operation dynamics of LECs are discussed.
