A solid state electrochemical light-emitting device has a high maximum luminance, a high external efficiency, a long half-life, and a low operating voltage. The device includes a solid layer of metal complex distributed in a polymer matrix. The solid layer is contacted by electrodes on each surface. An applied potential across the electrodes generates light with a luminance of at least 30 cd/m2. The light-emitting device can have external quantum efficiencies of at least 2.0%. A light-emitting circuit including an AC voltage waveform generator coupled to the electrodes of the device is also described.
