Abstract: In a discharge device containing at least In a discharge device containing at least one secondary emissive electrode, the latter comprises an emissive layer formed on a carrier of copper nickel alloy with at least 25 per cent nickel content, preferably 44-48 per cent.  In an example, copper-nickel sheet with a 45 per cent nickel content is rolled down to a thickness of 0.3 mms., punched into plates and the plates bent into the desired shape.  The plates are then treated with a "glazing mordant" (a mixture of strong acids and salts) to remove superficial impurities, coated electrolytically with copper to a thickness of 0.1 mm., mounted in the discharge tube, and the copper surface is oxidized in a glow discharge in oxygen to give cuprous oxide.  Caesium is then released from a pastil and reacts with the cuprous oxide, giving copper and caesium oxide; not all the cuprous oxide is reduced. Prior art secondary emissive electrodes having a copper or nickel base are referred to.  The Specification as open to inspection under Sect. 91 suggests that the copper-nickel alloy may contain a third metal of unspecified nature.
