Abstract :
The new method of photodynamic processes investigations in UV active media based on the analysis of the activator ions fluorescence decay is proposed. The excited-state photoionization spectra from 5d-state of Ce3+ ions in LiYF4 and LiLuF4 are determined. Photoelectrons and holes recombination and trapping cross-sections are estimated. The terminal state of excited-state photoionization is attributed to the 6s configuration of Ce3+, located in the conduction band of the host material.
