Abstract

CaF2:Yb2+ and SrF2:Yb2+ crystals have been investigated by a two-color UV + IR transient photoluminescence enhancement technique. The enhancement gives information about both changes in internal energy levels of the excitons and liberation of electrons from traps in the crystals. --------------------------------------------------------------------------------
