The luminescence in the vacuum‐UV from bulk polycrystals of Ne doped with Ar, Kr, and Xe is investigated. The exciting X‐rays produce free Ne host excitons which relax to their luminescing states. The guest atoms in the Ne matrix are excited, both by the free and by the relaxed excitons. The luminescence of the rare gas dopant atoms consisted of bands whose number, energies, and relative intensities are found not to change with any experimental parameter, in contrast to previous results. These luminescence bands are qualitatively explained to be due to atoms in a perturbing surrounding. Already at concentrations as low as 10 ppm, dimer formation is indicated by efficient luminescence from diatomic dopant molecules. All other observed luminescence is due to small contaminations of the supply gas and is found to be mainly due to oxygen and nitrogen.
