Abstract

Es wird eine Gasentladungslampe mit mindestens einer kapazitiven Einkoppelstruktur (2, 3) beschrieben, die sich insbesondere dadurch auszeichnet, dass die Einkoppelstruktur (2, 3) ein keramisches Material umfasst, das reines BaTiO3 aufweist. Insbesondere eine zusätzliche Dotierung von zumindest einem Teil von BaTiO3 mit Barium führt zu einem Material, dessen Curietemperatur und Sättigungspolarisation wesentlich höher und dessen Koerzitivfeldstärke wesentlich geringer ist, so dass eine Gasentladungslampe mit einer aus diesem Material hergestellten Einkoppelstruktur bei wesentlich höheren Temperaturen und einer geringeren Betriebsspannung betrieben werden kann. Weiterhin werden verschiedene Dotierungen des BaTiO3 mit Titan, Mangan und Blei beschrieben.
