Abstract
We have investigated the excited-state absorption spectra of four -doped materials: , , , and . The excited-state absorption in the emission region of each material is similar in nature to that previously observed for , 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.
