Luminescence and absorption spectra of LiF crystals with F[sub 2][sup -] color centers (CCs) were studied in the 14–300 K temperature range. The Huang–Rhys factors measured from absorption and emission spectra were equal in magnitude and calculated to be 3.2 and 2.72 at 77 and 300 K, respectively. It was shown that below 40 K inhomogeneous broadening of the zero phonon line of the F[sub 2][sup -] CC prevails over homogeneous broadening. Inhomogeneous broadening of the zero phonon line was observed to vary from 5 to 15 cm-1 for different crystal preparations. Persistent spectral hole burning stable at room temperature was realized in LiF:F[sub 2][sup -] crystals. © 2001 American Institute of Physics.

    This paper examines the effect of doping level on the X-ray luminescence of TbO-doped polycrystalline lithium tetraborate. It is shown that, when interpreting such spectra, it is convenient to proceed from the terms of free activator and constituent ions. We demonstrate that the emission lines...

    We have shown that in spatial structures based on color centers created by electrons in a lithium fluoride crystal, the distances between centers reach 1.6 nm and 3.6 nm for F1 and F2 centers respectively. This suggests considerable potential opportunities for using electron technology to form...
