Abstract
A controllable evaporation source of parent metal species, produced either from a volatile metal or a metal halide, and under some circumstances a chemical getter sink in a sealed RF excited discharge. This discharge occurs in a second, extremely pure gas which is present in great excess over the gas produced by evaporization which may be followed by chemical decomposition. Excitation of species whose emission is desired occurs by electron impact or energy transfer from the major species which are in turn, excited by the electron impact.
