摘要：

We have investigated the excited-state absorption spectra of four Eu2+-doped materials: CaF2, SrF2, SrCl2, and LiCaAlF6. The excited-state absorption in the emission region of each material is similar in nature to that previously observed for CaF2, and is suggested to arise from a 5d --> (conduction band) transition. An electrostatic model for the onset of this type of transition is successful in predicting trends among different hosts.
