    Abstract

    Submicron spherical SiO2 particles have been coated with AgEu(MoO4)2 phosphor layers by a sol-gel process, followed by surface reaction at high temperature, to get core/shell structured SiO2@AgEu(MoO4)2 particles. X-ray diffraction (XRD), Fourier-transformed infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FE-SEM), and transmission electron microscopy (TEM) were used to characterize the structure and morphology of the resulted core-shell phosphors. The luminescent properties of the core-shell structured phosphors have also been measured at room temperature, and their photoluminescence (PL) spectra are similar to the pure AgEu(MoO4)2 phosphor prepared by the same sol-gel method exhibiting red emission.
