Abstract
We investigated the recombination processes in the X-ray storage phosphor B aFBr:Eu2+ via the detection of the microwave-induced changes in the recombi nation luminescence in a high magnetic field. Resonances of the F(Br-) cent re, of the V-K(Br-2(-)) centre, of the Eu2+ ground state and of a hitherto unknown hole centre were observed. The luminescence band of the F(Br-) - V- K(Br-2(-)) recombination peaks at about 400 nm, that of the F(Br-)-new hole centre recombination at about 350 nm.
