title: A novel reddish-orange phosphor, NaLi2PO4:Eu3+.
abstract: A series of Eu(3+)-activated NaLi(2)PO(4) novel phosphors was synthesized by the solid-state reaction method. The X-ray diffraction (XRD) and photoluminescence (PL) properties of these phosphors were investigated at room temperature. The excitation spectra indicate that these phosphors can be effectively excited by near-UV (370-410 nm) light. The emission spectra exhibit strong reddish-orange performance, which is due to the (5)D(0) → (7)F(J) transitions of Eu(3+) ions. The orange emission from transition (5)D(0) → (7)F(1) is dominant over that of (5)D(0) → (7)F(2.) The concentration quenching of Eu(3+) was observed in NaLi(2)PO(4):Eu(3+) when the Eu concentration was at 1 mol%. The impact of doping Eu(3+) and photoluminescence properties were investigated and we propose a feasible interpretation.
