Abstract: | A novel phosphor BaY2Si3O10 (BYSO): Ce3+, Tb3+ was synthesized by the conventional solid-state reaction, which displays tunable color emission from blue to blue-green under ultraviolet excitation by adjusting the radio of Ce3+ and Tb3+ appropriately. Photoluminescence characteristics were carefully investigated. We demonstrate the existence of efficient energy transfer from Ce3+ to Tb3+ in BaY2Si3O10: Ce3+, Tb3+ phosphor. The energy transfer Ce3+ → Tb3+ was proved to be governed by dipole–quadrupole interaction. |
