Abstract

The recombination processes in the X-ray storage phosphor BaFBr:Eu²⁺ was investigated by measuring the microwave-induced changes in the recombination luminescence in a (high) magnetic field. Besides the resonances of the F(Br^-) centre, of the V_K(Br₂^-) centre and of the Eu²⁺ ground state we observed a line of a hitherto unknown hole centre. The maximum of the luminescence band in which the V_K(Br₂^-) centre could be detected was about 400 nm. The resonance of the unknown hole centre belongs to a luminescence band peaking at about 350 nm.
