| 摘要: 采用溶剂热法合成了一种单一相白色荧光粉NaY(WO4)2∶Eu3+，Tb3+，Tm3+。通过X射线衍射(XRD)、扫描电镜(SEM)、X射线能谱(EDS)及荧光光谱(PL)对制备的系列样品的物相、形貌和荧光性质进行了表征。结果表明：在荧光粉NaY(WO4)2∶x%Eu3+，4%Tb3+，1%Tm3+(x=5，10，15，20)中，随着Eu3+掺入量的增加，发光从绿光区进入白光区。同时观察到Tb3+到Eu3+的有效能量传递。 | |

| Abstract: 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%Eu3+, 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 Eu3+ can be observed. | |
