Hydrothermal Synthesis and Luminescent Properties of Eu3+,Tb3+ Co-Doped NaGd(WO4)2 Phosphors with Tunable Color
A series of NaGd0.96-x(WO4)2∶0.04Tb3+,xEu3+(x=0, 0.005, 0.01, 0.02, 0.04, 0.06, 0.08, 0.10, 0.12, 0.14, 0.16, 0.18) phosphors were prepared by a relatively mild hydrothermal method without the addition of any template. The phase structure, morphology and particle size, and luminescence properties of the samples were investigated by X-ray powder diffractometry (XRD), scanning electron microscopy (SEM) and fluorescence spectrophotometry, respectively. The results show that the as-synthesized samples are pure NaGd(WO4)2 with tetragonal scheelite structure, and possess defined square-plate morphology, uniform size distribution and good dispersity. All the samples can be excited effectively by near-ultraviolet light, and the emitting color can be tuned from green to red color by changing the doping concentration of Eu3+ and Tb3+.
