Eu2+-doped　Ba3La(PO4)3　phosphors　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)3　doped　slight　Eu2+　does　not　changed.　Ba3La1-x(PO4)3:x　Eu2+　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　Dexter＇s　theory,　it　was　found　that　the　major　mechanism　for　concentration　quenching　as　a　result　of　dipole-dipole　(d-d)　interaction.　©　(2013)　Trans　Tech　Publications,　Switzerland.
