Abstract
The recombination processes in the x-ray storage phosphor BaBr2:Eu2+were investigated by optical and magneto-optical methods. A structure-sensitiveinvestigation of the defects involved in the recombination processes wasperformed by detecting the microwave-induced changes in the recombinationluminescence in a high magnetic field. F centres as well as VKhole centres are created after x-irradiation at low temperatures. The low-energyrecombination band peaking at about 460 nm is due to F–VKcentre recombinations, whereas the two high energy bands at 282 and 315nm are probably due to recombinations of self-trapped excitons.
