Abstract
The recombination processes in the X-ray storage phosphor BaFBr:Eu2+ w as investigated by measuring the microwave-induced changes in the reco mbination luminescence in a (high) magnetic field. Besides the resonan ces of the F(Br-) centre, of the V-K(Br-2(-)) centre and of the Eu2+ g round state we observed a line of a hitherto unknown hole centre. The maximum of the luminescence band in which the V-K(Br-2(-)) centre coul d be detected was about 400 nm. The resonance of the unknown hole cent re belongs to a luminescence band peaking at about 350 nm. (C) 1998 El sevier Science Ltd. All rights reserved.
