| Abstract: | The crystals of fluorite:Eu 2+ that can emit blue fluorescence can be made by sintering with fluorite doped Eu in reducing atmosphere.Eu and F i point-defects can be found in 011]direction of high symmetry in fluorite:Eu 2+ crystals. In general they have little affect on luminescent object . Partially gathering crystal-cluster of Eu and F i in 1-12]013]direction of low symmetry have important affect on luminescence.Boundary between crystal-cluster of Eu 2+ and matrix can produce energy level of localized region. |
