In the photoluminescence (PL) of BaFBr:Eu2+,Eu3+,the emissions of Eu2+,carrier electron-hole (e-h) recombination, andEu3+are observed, while in the photostimulated luminescence (PSL) only the emission ofEu2+is exhibited. This disappearance of e-h recombination in PSL is considered to be caused by carrier migration during photo-stimulation. ©1997 American Institute of Physics.
