“…We suppose that the 0.27 eV activation energy of this glow peak corresponds to the diffusion energy of the V K centres. A similar situation occurs in KI irradiated at 80 K: the V K diffusion energy of 0.273 eV [17] agrees quite well with the 0.27 eV activation energy of the 105 K glow peak [18].…”

The recombination processes in the x-ray storage phosphor BaBr 2 :Eu 2+ were investigated by optical and magneto-optical methods. A structure-sensitive investigation of the defects involved in the recombination processes was performed by detecting the microwave-induced changes in the recombination luminescence in a high magnetic field. F centres as well as V K hole centres are created after x-irradiation at low temperatures. The low-energy recombination band peaking at about 460 nm is due to F-V K centre recombinations, whereas the two high energy bands at 282 and 315 nm are probably due to recombinations of self-trapped excitons.
