LOW-PRESSURE GAS DISCHARGE LAMP WITH ELECTRON EMITTER SUBSTANCES SIMILAR TO BATIO3

摘要

A low-pressure gas discharge lamp is described, which is equipped with a gas-discharge vessel containing an inert gas filling as the buffer gas and an indium, thallium and/or copper halide, and with electrodes and with means for generating and maintaining a low-pressure gas discharge, which has as the electron emitter substance a compound selected from the group of ABO>3< OR A>n<BO>2+n<, A>n<C>25+n<, OR A>n<D>23+n<, wherein: A = an alkaline earth element or a mixture of several different alkaline earth elements, B = cerium, titanium, zirconium, hafnium, or a mixture of these elements, C = vanadium, niobium, tantalum, or a mixture of these elements, D = scandium, yttrium, lanthanum, a rare earth element, or a mixture of these elements.
