BaLiF3:Eu2+一种新型X射线存贮材料

BaLiF3:Eu2+ A PROMISING X-RAY STORAGE PHOSPHOR

    摘要
  • 摘要: BaLiF3微晶经X射线辐照所产生的热释光,在日光下照射15分钟或在室温条件下放置2~3天都会消失,表明X射线对BaLiF3微晶的辐照损伤是轻微的,易擦除的。实验还发现BaLiF3:Eu2+具有光激励发光特性,因此可以认为BaLiF3:Eu2+是一种具有潜在应用价值的新型X射线存贮材料。

     

    Abstract: The TSL glow of X-ray irradiated BaLiF3 crystallite vanished within 15 minutes of sunlight bleaching or after 2~3 days of room temperature annealing, which indicate that its X-ray irradiation damage is slight and can be easily erased. It is also found that BaLiF3:Eu2+ is a photostimulative, and it seems to be a promising X-ray storage phosphor for practical utilization.
