A series of Tb3+doped NaY(MoO4)2are synthesized by a solid-state reaction at 550 °C for 4 h, and their luminescent properties are investigated. The phase formation is carried out with X-ray powder diffraction analysis, and there is no other crystalline phase except NaY(MoO4)2. NaY(MoO4)2:Tb3+can produce the green emission under 290 nm radiation excitation, and the luminescence emission peak at 545 nm corresponds to the 5D4→7F5 transition of Tb3+. The emission intensity of Tb3+in NaY(MoO4)2is enhanced with the increase of Tb3+concentration, and there is no concentration quenching effect. The phenomena are proved by the decay curves of Tb3+. Moreover, the Commission International de I’Eclairage (CIE) chromaticity coordinates of NaY(MoO4)2:Tb3+locate in the green region.

A novel white-bluish emitting phosphor of Ba0.49Sr0.49)2-B2P2O10:0.02Eu2+is synthesized by the solid state reaction. Ba0.49Sr0.49)2-B2P2O10:0.02Eu2+can be effectively excited by 370 nm ultraviolet (UV) light, and exhibits two emission bands at 430 nm and 522 nm which are attributed to the d-f transitions of the Eu2+ ions in two different cation sites in the host lattices. And the chromaticity coordinate of Ba0.49Sr0.49)2-B2P2O10:0.02Eu2+phosphor is (0.29, 0.25).
