Abstract: We report on photoionization measurements of three Ce3+ doped chlorides: Cs3LuCl6, Cs2LiLuCl6 and Cs2LiYCl6. These chlorides are hygroscopic and must be kept hermetically sealed in quartz vials, complicating the use of standard techniques to determine electron transfer processes. Thus, a solely optical technique, based on thermoluminescence excitation spectroscopy, is applied to detect the photoionization energies of Ce3+ in the three compounds.
