Abstract

The investigations on photoluminescence and cathodoluminescence reveal that phosphor Ca6Gd1.5Tb0.5Na2(PO4)6F2 (CGPF-Tb) shows an intense green emission. Under the same conditions, the relative luminance of this phosphor is about 62%, 127%, and 71% of that of commercial phosphor Zn2SiO4:Mn (ZSM) under 147 and 172 nm vacuum ultraviolet (VUV) light, and 2.5  kV/100μA  cm2 cathode ray excitation, respectively. A shorter luminescence decay time (τ1/106.1  ms) makes it more suitable for displays application than ZSM. Hence CGPF-Tb is a promising candidate as a green-emitting component for applications in plasma display panels and field emission displays.
