英文摘要	Series of NaLa(PO3)(4):Tb3+/Eu3+ phosphors were prepared by a hightemperature solid-state reaction technique. Structure refinements were performed based on powder X-ray diffraction (XRD) data. VUV-UV-vis photoluminescence (PL), fluorescence decays, time-resolved emission spectra (TRES), and low-voltage cathodoluminescence (CL) spectra were utilized to investigate the luminescence and energy transfer processes. Under VUV-UV light and low-voltage electron beam excitation, NaLa(PO3)(4):Tb3+ and NaLa(PO3)(4):Eu3+ exhibit characteristic emissions of Tb3+ (D-5(4) --> F-7(J)) and Eu3+ (D-5(0) --> F-7(J)), respectively. By adjusting the doping concentration of Eu3+ ions in NaTb0.70La(0.30-x)Eux(PO3)(4), tunable emission colors are realized in a large color gamut, in which energy transfer from Tb3+ to Eu3+ was observed and discussed in detail. On the basis of the good VUV-vis PL and CL properties, NaLa(PO3)(4):Tb3+/Eu3+ phosphors might be promising for applications in plasma display panels (PDPs) and field emission displays (FEDs).
