Spectral and kinetic characteristics of photoluminescence of BaF
2
and SrF
2
crystals implanted with high-energy (∼100 keV) Ag ions were studied. The photoluminescence spectra of both crystals have a similar structure, in which three components are observed with maxima in the wavelength ranges 500–550, 600–670, and 760–770 nm. The positions of the maxima depend on the material of the matrix and the excitation wavelength. The kinetic curves of luminescence decay also exhibit three components with characteristic decay times of ≤1, about 4, and 13–15 ns.
