In this paper, we present the VUV-vis spectroscopic properties of Na2GdF2PO4:Tb 3+ phosphors prepared at 700 °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 Na2Gd1-x Tb x F2PO4 can be considered as promising candidates for plasma display panels (PDPs) and Hg-free fluorescent tubes application.
