The luminescence excitation and emission spectra of SrCl2:Pr single crystals containing 0.2 mol. % Pr were investigated at T=10 K using vacuum ultraviolet synchrotron radiation. From analysis of the fine structure of the low-energy excitation band of an activator, the following main frequencies associated with the local structure of the activator centers were found in the phonon spectrum of SrCl2:Pr crystal: 194; 210; 266 and 298 cm–1.
