Abstract

We have synthesized Eu³⁺-doped YVO₄ phosphors by using a hydrothermal method and investigated their luminescent properties. Aqueous solutions of Y₂O₃, V₂O₅, Eu₂O₃, and nitric acid with various pH values were used as the precursors. The crystallinity, surface condition, and emission characteristics were examined using XRD, FT-IR, and photo-excited spectrometer. Eu³⁺ incorporation followed by the efficient red emission strongly depends on the acidity of solution media. The emission intensity becomes stronger as the pH values increase to 7 and then gradually decreases. This phenomenon might be related to the hydroxyl quenching effect, which is induced by surface bound OH- groups.
