Investigation of Na3GdP2O8:Tb3+ as a potential green-emitting phosphor for plasma display panels

► Na3Gd1−xTbxP2O8 solid solutions with a monoclinic structure. ► A high photoluminescence quenching concentration under VUV and UV-light excitation. ► A short decay time and a bright green emission under 147 nm light excitation.
