Abstract
Electrical sparks are studied which occur when ferroelectric TGS crystals are heated through the Curie point. The light comes from electrical discharges into the surrounding atmosphere. A rough surface of the crystal and the configuration of the domains have a very strong influence on this effect. Similar sparks are found at the edge of the electrode when the polarization is reversed by an electrical voltage being greater than a certain critical value. A mechanism is proposed which describes these phenomena.Keywords
