Ca6Gd1.5Tb0.5Na2(PO4)6F2--an intense green-emitting phosphor under vacuum ultraviolet and low-voltage cathode ray excitation.
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 microA cm(-2) cathode ray excitation, respectively. A shorter luminescence decay time (tau(1/10) approximately 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.
