More Information
Summary:This invention announces a novel aluminate phosphor and the process for preparing the aluminate phosphor. The phosphors exhibit an enhanced luminescence properties by substitution of Al/F by Si/O. The chemical composition of the aluminate phosphor is CaaSrbBacAldSieOfFgRh. R represents at least one or more elements selected from the group consisting of rare earth elements. In addition, structure of the phosphor in this invention can be tune via substitution of Al/F by Si/O, controlling the ratio of various valence of rare earth elements can adjust the luminescence properties.
