【 摘 要 】

The paper is focused on an influence of vanadium ions on the up-conversion processes in nanosized YVxP1-xO4 solid state solution. As a consequence, two series of YVxP1-xO4 (where x = 0-1) materials has been obtained via co-precipitation method. Yttrium orthovanadate-phosphate has been co-doped with the up-converting Er3+-Yb(3+ )and Tm3+-Yb3+ lanthanide ion pairs. Obtained series of nanosized materials has been investigated for phase purity, chemical composition, morphology by the means of X-Ray Powder Diffraction (XRD) and Scanning Electron Microscope (SEM). Photoluminescence properties of 0.25 mol% Tm3+, 20 mol% Yb3+:YVxP1-xO4 (x = 0, 0.3, 0.4, 0.5, 0.6, 0.7, 1), and 1 mol% Er3+, 20 mol% Yb3+:YVxP1-xO4 (x = 0, 0.3, 0.4, 0.5, 0.6, 0.7, 1) were investigated in detail. It has been found that increase of the vanadium content leading to better up-conversion luminescence. (C) 2021 The Author(s). Published by Elsevier B.V.
