Abstract
Eu2+-doped Ba3La (PO4)3phosphors were synthesized by solid-state reaction method. The X-ray diffraction (XRD) results showed that the obtained phosphors were cubic phase. The structure of Ba3La (PO4)3doped slight Eu2+does not changed. Ba3La1-x(PO4)3:xEu2+phosphor can be excited by UV-visible light, which emits intensely blue light with broadband peaked at about 466 nm. The relative PL intensity increases with Eu2+-concentration increasing until a maximum intensity is reached, at about x=0.015mol. According to the Dexters theory, it was found that the major mechanism for concentration quenching as a result of dipole-dipole (d-d) interaction.
