| Abstract: | The photostimulated luminescence (PSL) of Eu2+: BaF.Cl2-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+:BaF.Cl2-x phosphors are given. Utilizing this method, westudied further the dependence of the density ratios and phtotstimulated cross-section ratiosof the two kinds of F color centers on the F/Cl ratios. |
