The photostimulated luminescence (PSL) of Eu2+:BaFxCl2-x (x=0.90,0.95, 1.00, 1.05, 1.10, 1.15) phosphors under UV-irradiation is reported. Throughchanging the stimulated mode and scan direction of the stimulating light, the measurementmethod of the density ratios and photostimulated cross-section of the two kinds of F colorcenters during the PSL of Eu2+:BaFxCl2-x phosphors are given. Utilizing this method, westudied further the dependence of the density ratios and phtotstimulated cross-section ratios of the two kinds of F color centers on the F/Cl ratios.
