8%Eu3+/y%Eu3+,5%Tb3+(y=1, 3, 5, 7, 9)codoped NaLu(WO4)2-x(MoO4)x (x=0, 0.5, 1.0, 1.5, 2.0) phosphor were prepared via microemulsion method at room temperature. X-ray diffraction (XRD), scanning electron microscopy (SEM) and fluorescence spectroscopy were used to characterize the samples. The XRDof as-prepared samples were in agreement with the PDF#27-0729, showing that sample was the scheelite structure, belongs to the tetragonal crystal system. SEMimages showed that the as-prepared particles were shuttle. Particle size was about 110 nm. The critical activator molar concentration (Eu3+) in NaLu(WO4)(MoO4):Eu3+ was 8%. As the Mo content increased, the intensity of emission of Eu3+ activated at wavelength of 394 nm and 466 nm increased and reached a maximum when the relative ratio of nMo/nW was 1:1. The intense red-emission of the tungstomolybdate phosphors at near-UVand blue excitation suggested that the material was a potential candidate for white light emitting diode (WLEDs). This phosphor excited by 268, 394 and 466 nm, exhibited orange-red, yellow and pale yellow respectively, meeting the needs of the different light color. In the systems of NaLu(WO4)(MoO4):y%Eu3+,5%Tb3+(y=1, 3, 5, 7, 9) phosphors, with the increase of the doped concentration of Eu3+(y), the emission color of the co-doped NaLu(WO4)(MoO4) phosphors can be tuned precisely from green (x=0.278, y=0.514)to white (x=0.356, y=0.373), (x=0.385, y=0.313). At the same time, a very efficient energy-transfer from Tb3+ to Eu3+ can be observed.
