We have investigated the excited-state absorption spectra of four Eu[sup 2+]-doped materials: CaF[sub 2], SrF[sub 2], SrCl[sub 2], and LiCaAlF[sub 6]. The excited-state absorption in the emission region of each material is similar in nature to that previously observed for CaF[sub 2], and is suggested to arise from a 5[ital d][r arrow] (conduction band) transition. An electrostatic model for the onset of this type of transition is successful in predicting trends among different hosts.
