Abstract

We investigated the recombination processes in the X-ray storage phosphor BaFBr:Eu²⁺ via the detection of the microwave-induced changes in the recombination luminescence in a high magnetic field. Resonances of the F(Br^-) centre, of the V_K(Br₂^-) centre, of the Eu²⁺ ground state and of a hitherto unknown hole centre were observed. The luminescence band of the F(Br^-)-V_K(Br₂^-) recombination peaks at about 400 nm, that of the F(Br^-)-new hole centre recombination at about 350 nm.
