| Abstract: | Two long-lived excited level contributions are evidenced in the emission spectra of substitutional57Fe2+ ions in CaF2. One originates from the Γ4 triplet of the5E state, whose relaxation properties are analysed by absorption spectroscopy and the other is probably emitted by the lowest
Γ5 triplet of the5T2 state. Other after-effects, including a Fe+ state, are observed. |
