• The spectroscopic properties SrF 2–Eu(1%), SrF 2–Er(1%) and nominal pure SrF 2 crystals have been studied using time-resolved vacuum ultraviolet (VUV) spectroscopy under pulsed synchrotron radiation excitation. The 4f k↔4f k−15d (f–d) and 4f k↔4f k (f−f) excitation spectra and emission spectra (with and without of time resolution) have been investigated in the wide energy region at 8 and 295 K. Moreover, the emission and excitation behaviors of intrinsic luminescence SrF 2 have been studied at 8 K, when the fast and slow components given by singlet and triplet relaxation of self-trapped excitons (STE) are observed. Special attention is devoted to VUV emission of Er 3+-doped SrF 2 due to spin-allowed and spin-forbidden 4f 105d→4f 11 transitions.
