Continuous radiation of excimer complexes in argon and neon crystals

This research is devoted to an analysis of continuous luminescence spectra of argon and neon crystals in the ranges 4-7 and 9-17 eV, respectively. The experimental results of this research are compared comprehensively with the data on the gaseous phase and with the luminescence of exciplexes of inert-gas halogenides. It is proposed on the basis of the detailed comparison of different experimental data that the continuum with a peak at 6.2 eV can be identified with radiation decay of the excimer complex Ar2+O-. The formation of a similar exciprex Ne2+O- with charge transfer is observed in the neon matrix doped strongly with oxygen. (C) 1998 American Institute of Physics.
