Abstract:
A new method to determine the concentration of the defect centers in
photostimurable luminescent materials is demonstrated. The method is representatively applied to BaFCl:Eu 2+ and KCl:Eu 2+ single
crystals, which exhibt the photostimulable luminescence. Thereby the values of the oscillator strength, f , are calculated
utilizing the results of the defect center concentrations as well as the measured refractive indices and the corresponding absorption bands
by using the Smakula's formula. The values obtained are f =0.80 for
the F(Cl - ) centers in BaFCl:Eu 2+ and f =0.60 for the F centers
in KCl:Eu 2+ .
