【摘要】 X线影像板需要近红外光激励．掺入Ca2＋，S2＋，Mg2＋后，用650～700um光激励BaFX：Eu2＋，可以更为灵敏．用正电子湮没寿命谱，电子顺磁共振谱，加热发光谱和光激励发光谱，研究了X射线辐照后BaFx：Eu（X：CI，Br）电子陷阱的性质、状态、密度和转换．更多还原

【Abstract】 The X-ray image Plate will need near infrared light to stimulate. BaFBr:Eu2+may be sensitive to stimulate further into 650-700 urn by doping with Ca2+,Sr2+,Mg2+. It is shown by positron annihilation lifetime, electron paramagnetic resonance, thermoluminescence and photostimulation luminescence that upon X-ray irradiation the nature states,density and charge of the photostimulatable electron traps in BaFX: Eu(X: Cl,Br)have been studied arter x-ray irradiation.更多还原
