| Description |
Ba2Y0.67-xTbxV2O8 (x = 0.0-0.3) phosphors were produced by a solid-state methodology. The obtained compounds were isostructural with Ba3V2O8. The UV excited Ba2Y0.67-xTbxV2O8 phosphors exhibited a wide emission band centered at 440 nm realized for the VO4](3) groups, and an intense green emission (545 nm) of Tb3+ ions. The host emission diminished and that of Tb3+ amplified with increasing the Tb3+-dopant up to a certain level of Tb3+ concentration owing to the energy transfer (ET) occurrences. Meanwhile, the coloring parameters navigated from the blue to the bluish-white. The presented strategy of fine-tuning the photoluminescence via the vanadate to Tb3+ ET could deliver potential white light-emitting systems. (C) 2020 Elsevier B.V. All rights reserved.
