Abstract
A low-pressure gas discharge lamp having a gas discharge vessel containing a gas filling including a copper compound. The copper compound is selected from the oxides, chalcogenides, hydroxides, hydrides and the metalorganic compounds of copper. In addition to the copper compound, the gas filling includes a buffer gas such as argon, and may also include a thallium compound and/or a copper halogenide.
