Add to ORKGCaF2: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. (c) 2011 Elsevier B.V. All rights reserved
