摘要

讨论了光激励发光材料ＢａＦｘＣｌ２－ｘ：Ｅｕ２＋中的缺陷与正电子湮没寿命的关系．通过实验结出随着ｘ值的改变即Ｆ／Ｃｌ比值的变化对形成Ｆ色心的影响，并且给出了ｘ值与Ｆ色心的种类与浓度的关系．

Abstract

The relation between positron annihilation lifetime and defects in BaFxCl2-x:Eu2+ phosphors is studied. The experimental result shows that the formation of F centers is influenced by the x value （or the F/Cl ratio） of the samples. The relation between the x value and the type and concentration of F centers is also presented.
