“…It was shown that the exciplex states B 2 1/2 and X 2 1/2 can be effectively populated via host excitons resulting in B 2 1/2 → X 2 1/2 emission bands at 196.5 and 211.2 nm in Ne and Ar matrices, respectively. The spectra indicated a red shift in energy of 0.4-0.8 eV compared with the gas phase results [2][3][4][5][6][7][8][9][10][11][12] due to the dielectric interaction with the host. An emission band at 227 nm for CsF in a Ne matrix was assigned to the C 2 1/2 → A 2 1/2 transition, too.…”

Pulsed electron-beam excitation of solid Ne films doped with 0.4 - 0.6% CsCl leads to fluorescence bands in the deep UV region. The strongest band at 220.1 nm (FWHM 13 nm) is assigned to the transition and a much weaker one at 249.2 nm (FWHM 15 nm) to the transition of the ions on the basis of transition energies (including dipole solvation) and line shapes. The 220.1 nm band provides a large cross section for stimulated emission of and the band intensity depends strongly on the CsCl content, with optimal values similar to that obtained for CsF. The homonuclear ) transition at 263.2 nm indicates that pre-dissociation occurs via the state.

“…VUV and XUV transitions have already been observed for the excimers of the alkalihalide ions which are isoelectronic to the neutral rare-gas halides. [13][14][15]36 VUV/XUV emissions can also be expected from ionic rare-gas alkali excimers which are isoelectronic to the rare-gas dimers. 46 The upper state is an ionic molecule fovmed by combining a rare-gas ion Rg with a ground state alkali atom A.…”
