In this paper, we present the VUV-vis spectroscopic properties of Na(2)GdF(2)PO(4):Tb(3+) phosphors prepared at 700 degrees C. The phosphors exhibit some favorable luminescence characteristics such as intensive and broad absorption near 147/172 nm, high bright emission in whole doping concentration, and tunable chromaticity coordinates from blue to whitish and further to yellowish-green range by changing the doping concentration of Tb(3+). As a result, this series of phosphors Na(2)Gd(1-x)Tb(x)F(2)PO(4) can be considered as promising candidates for plasma display panels (PDPs) and Hg-free fluorescent tubes application.
