Abstract
<p>Light emission from the metal electrodes cathodically polarized at cell voltages up to 250 V was investigated in various aqueous electrolyte solutions. The light emission was observed when the temperature of electrodes exceeded the boiling temperature of the electrolyte due to the intense cathodic polarization: a thin vapor layer was formed at the metal/electrolyte interface in which a high electric field ionized vapor molecules to generate the plasma state. The light emission was caused by a glow discharge at relatively low cell voltages and by a spark discharge at high cell voltages. The spectra of the emitted light were assigned to the constituents of the electrolyte solution, electrode material and gaseous hydrogen evolved at the electrode.</p>
