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 LiSrAlF6 to 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 LiSrAlF6 crystals and mixed LiSrxCa1-xAlF6 with an increase in the concentration of Ce3+ ions.
