Rare-earth-activated BaY2Si3O10 (BYSO) phosphors were synthesized via a solid-state reaction. BaY2Si 3O10:Ce3+ yields an indigo-blue emission peak at 404 nm according to excitation at 334 nm attributed to the Ce3+ 4f→5d transition. BaY2Si3O10:Tb 3+ typically generates green emission peaks resulting from the 5D47Fj transition. BaY 2Si3O10:Eu3+ exhibits red emission peaks upon excitation at 393 nm. The quantum efficiency of these phosphors was found to be 53%, 55%, and 63% of commodity. The results in this work demonstrate that these phosphors with new compositions are good candidate luminescent materials for use in plasma display panels and light-emitting diodes, excited from VUV to UV.
