| 摘 要： | 本文研究了BaFCl:Eu2+在不同波长的紫外线辐照和不同的测定温度下的光激励发光性质.通过改变激励方式及激励光的扫描方向,给出了BaFCl:Eu2+光激励发光过程中,两种F色心的浓度比值和光激励截面比值与紫外线辐照波长和测定温度的关系.同时我们还研究了在激励读出过程中,对应两种F色心的光激励发光强度与激励温度的关系,并且给出了相应于F(Cl-)心的热激活能.

| Abstract: | The photostimulated luminescence(PSL) of BaFCl: Eu2+ phosphors under UV-irradiation is reported. Through changing the stimulable mode and scan direction of the stimulable light, the dependence o.f the density ratios and photostimulation cross section ratio of the two kinds of F color centers on irradiation wavelength and stimulation readout temperature during,the PSL of BaFCl: Eu2+ phosphors are given. Meanwhile the dependence of PSL intensity corresponding to the two kinds of F color centers on stimulation readout tempelature are studied, and active energy corresponding to F(Cl-) center is also calculated. |
