摘要：
NaY(WO4)(2) co-doped with Eu3+, Tb3+ and Tm3+ ions white light phosphors were synthesized by solvothermal method. The morphology, phases and optical properties were investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD), X-ray energy dispersive spectroscopy (EDS), and photoluminescent (PL) spectroscopy. The results indicated that in the systems of NaY(WO4)(2):x%Eu2+, 4%Tb3+, 1%Tm3+ (x=5, 10, 15, 20) phosphors, with the increase of the doped concentration of europium ions, the emission color of the co-doped NaY(WO4)(2) phosphors can be tuned precisely from green to white. At the same time, a very efficient energy transfer from Tb3+ to De can be observed.
