Europium-activated barium halides, especially BaFBr:Eu are used as photostimulable x-ray phosphors in computerized radiography. The kinetics of the photostimulated luminescence (PSL) has been investigated. The measurements support the mechanism of PSL involving F/sup +/ equivalent F and Eu/sup 2+/ equivalent Eu/sup 3+/ centers. Values for the cross section of optical excitation of trapped electrons and for the calculated oscillator strength have been determined.
