| 1. A method of constructing an improved, electrically excited, gas discharge lamp, comprising the steps of:
constructing a lamp envelope;
cleaning said lamp envelope; and
filling said envelope with a gas mixture comprising least one IR-active gas species, said at least one gas species being such
that said lamp provides an output characteristic of spontaneous emission of said at least one gas species to a around state
when excited; and
the improvement being the additional step of depositing a metallic catalytic material in a finely divided form on the inside
of said lamp envelope, such that it forms a non-conducting film.
