    • In regard to LiF, the fits were carried out in the range of ∼2.10-2.60 eV so as to avoid the region of the F3+ emission band possibly affected by the overlap with the signal due to F2.

    • The lifetimes predicted by the model were estimated by least-squares fitting the decay curves (not reported) predicted by Eq. 9 at different emission energies with a single exponential. It is worth noting that the simulated data (as real data) feature no appreciable nonexponential behavior in the time scale of experimental data, at least when the parameters of the model are close to the best-fit ones.

    • As explained above, the homogeneous shape is obtained by a convolution of the discrete Poissonian with a narrow Gaussian curve of half width ωp to take into account further homogeneous broadening effects and experimental bandwidth.
