Popis: The spectral properties of two-component Ca1−xSrxF2:Ce3+(0.05 mol%) (x = 0.75, 0.41, 0.25, 0.14) crystals in UV spectral region were investigated. It was shown that spectral properties of Ca1−xSrxF2:Ce3+(0.05 mol%) in UV spectral region have intermediate position between those for pure CaF2 and SrF2 crystals. The optical constants were calculated from reflectance spectrum for CaF2, SrF2, Ca1−xSrxF2:Ce3+(0.05 mol%) (x = 0.75, 0.25) crystals by use of Kramers-Kronig relations for complex reflection coefficient and Fresnel formulas.
