摘要: Abstract The new green-emitting phosphors Na 3 Y 1 − x Si O 9 : Tb 3+ (0.05 ≦ × ≦ 0.50) were developed by a solid-state reaction in this study. excitation VUV region showed broad band 150–180 nm with the strong absorption at around 149 and 178 nm, which are adjacent to light sources of 147 172 nm. composition 0.6 :0.4Tb was observed have strongest emission 541 nm. It higher intensity, comparable brightness much shorter decay time under 147 nm when compared commercial Zn 2 SiO 4 :Mn 2+ green phosphor. results indicated that YSi :Tb could be potential candidate as
