A montmorillonite inorgano-intercalation compound(MIIC) was synthesized by using a purified Na-exchanged bentonite(PNaB) as a matrix and Al-pillaring ion as an
Europium(Ⅲ)-doped YF_3 is prepared by a hydrothermal process at 200℃.X-ray diffraction(XRD) pattern identifies the formation of YF_3 phase without detectable
