A new technique for studying excited-state photoionization spectra of activator ions in dielectric hosts is proposed. It is based on the analysis of fluorescence kinetic dependences on excitation wavelength. Results of the investigation of 5d–4f fluorescence kinetics of $\mathrm{Ce}^{3+}$ ions in double fluoride scheelite type crystals are adduced. Excited-state absorption spectra from 5d-state of $\mathrm{Ce}^{3+}$ ions in $\mathrm{LiMeF}_4$ ($\mathrm{Me}=\mathrm{Y,Lu}$) single crystals and pump-induced color center photoionization spectra are demonstrated. Photoelectrons and holes recombination and their trapping by crystalline defects cross sections estimations are performed.
Keywords:
excited-state absorption, photoionization of activator ions, solarization, recombination, fluorescence kinetics.
