Abstract

The investigations on photoluminescence and cathodoluminescence reveal that phosphor Ca 6 Gd 1.5 Tb 0.5 Na 2 ( PO 4 ) 6 F 2 (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 Zn 2 SiO 4 : Mn (ZSM) under 147 and 172 nm vacuum ultraviolet (VUV) light, and 2.5   kV / 100 μ A   cm 2 cathode ray excitation, respectively. A shorter luminescence decay time ( τ 1 / 10 6.1   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.
