Ionic chromophores Xe⁺p (p≤ 4) in multishell rare-gas clusters Xem(NF₃)kNe₇₅₀₀ (m, k ≤ 100) studied with fluorescence spectroscopy
We have studied fluorescence spectra of small Xem and Xem(NF3)k clusters (m, k ≤ 10²) embedded in large host Ne₇₅₀₀ clusters, excited with SR excitation in the VUV spectral region above the Xe⁺(²P₁/₂) atomic limit. The IR emission bands due to ionic chromophores Xe⁺p (p = 2, 3, 4) as well as UV (...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | We have studied fluorescence spectra of small Xem and Xem(NF3)k clusters (m, k ≤ 10²) embedded
in large host Ne₇₅₀₀ clusters, excited with SR excitation in the VUV spectral region above the
Xe⁺(²P₁/₂) atomic limit. The IR emission bands due to ionic chromophores Xe⁺p (p = 2, 3, 4) as
well as UV (B–X) and visible (C–A) bands due to desorbed Xe⁺F⁻– excimer molecules have been
observed. The triatomic Xe₂F excimer emission has only been observed under low-energy excitation
close to the lowest xenon exciton absorption band. A competition between ionic and
charge-transfer reaction channels is followed as a function of the cluster sizes m and k. |
