二价铕激活的氟氯化钡是一种高效率的X射线发光材料。Stevels和Pingault曾研究过BaFCl:Eu~(2+)在X射线激发下的发光性质。E.I.Du Pont公司用BaFCl:Eu~(2+)制成X射线照像用增感屏。 制备BaFCl:Eu~(2+),文献报导多是采用将相应的组分混合均匀然后在高温下焙烧的 Bivalent europium activated barium fluoride is a highly efficient x-ray emitting material. Stevels and Pingault have studied the luminescent properties of BaFCl: Eu ~ (2+) under X-ray excitation. E.I. Du Pont company with BaFCl: Eu ~ (2+) made by the X-ray image sensing screen. Preparation of BaFCl: Eu ~ (2 +), the literature is mostly prepared by mixing the corresponding components and then calcined at high temperature
