Abstract

Eu-doped LiBaPO4 phosphors were synthesized by sol gel route using PVA as the chelating agent. The structure and photoluminescence (PL) properties of the as-prepared LiBaPO4 phosphors were investigated by X-ray diffraction (XRD), X-ray absorption spectroscopy (XAS) and PL spectroscopy. The samples presented single hexagonal phase and the incorporation of the excess Li did not affect the crystal structure. The luminescence properties of the Eu-doped LiBaPO4 phosphors strongly depend on the Li concentration. It is possible that the Li excess contributes to the Eu3+ -> Eu2+ reduction and enhances the Eu2+ stabilization in the LiBaPO4 structure. (AU)
