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.
