Abstract

It was demonstrated that the amount of Ce³⁺ ions in centers with luminescence in the shorter wavelength region decreases and with luminescence in the longer wavelength increases upon transition from LiSrAlF₆to the LiCaAlF₆ matrix. In this case, the longer wavelength edge of the excitation band corresponds to the luminescence of longer wave centers in the LiCaAlF₆ matrix, while the opposite is observed for the LiSrAlF₆ matrix. The picture also changes with an increase in the concentration of Ce³⁺ ions, namely, an increase in the luminescence intensity of longer-wave centers is observed; It is shown that mixed crystals at a low concentration of Ce³⁺ ions are characterized by a higher gain. In this case, the effect of the formation of color centers and induced absorption appears for LiSrAlF₆crystals and mixed LiSr_xCa_1-xAlF₆ with an increase in the concentration of Ce³⁺ ions.
