SiO2@LaPO4:Eu3+ core–shell phosphors have been successfully synthesized by a one-step and economical wet-chemical route at low temperature. The as-obtained products were characterized by means of photoluminescence spectroscopy (PL), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), selected area electron diffraction (SAED), scanning electron microscopy...
In this paper, a series of Ca3-x-ySry(PO4)2:xEu2+, (0≤x≤0.075, 0≤y≤2.2) phosphors were prepared by flux assisted solid-state reaction method, and their photoluminescence properties were investigated. The β- to β′-phase transition of Ca3-ySry(PO4)2 for high Sr2+ content was observed from the XRD patterns, and the corresponding optical bandgaps were obtained experimentally. Various Eu2+ emission centers...
