Single crystal of lithium terbium tungstate LiTb(WO4)2 has been grown by the flux method.The crystal structure was refined from single-crystal X-ray data.It crystallizes in tetragonal system,space group Ⅰ41/a with a =5.1749(9),c =11.1953(19) (A),V=299.81(12) (A)3,Z=2,Mr =661.56,Dc =7.328 g/cm3,F(000) =560,μ(MoKa) =49.94 mm-1,R(F2 ＞ 2σ(F2)) =0.026 and wR(F2) =0.070.It features a typical scheelite-type structure composed of two-direction packing of isolated WO4 tetrahedra.Li and Tb atoms in the structure occupy the same crystallographic site.Moreover,a series of solid solution phosphors LiTb1-xEux(WO4)2 (x =0.004～0.1) were synthesized by high temperature solid-state reactions.The phosphors could be effectively excited by a wavelength range from 379 to 487 nm,which matches well with the UV and near-UV LED chip.The emission color of the phosphor can be tuned from green,through yellow to red by simply adjusting the relative Eu3+ and Tb3+ concentration due to the Tb3+ to Eu3+ energy transfer.
