New solid solutions, Li_xY(VO₄)_1-xF_4x (0 < x ≤ 0.1), were successfully prepared via solid state reaction method by combination of orthovanadate YVO₄ (Zircon structure) and LiYF₄ fluoride (Scheelite structure). The structures were determined by X-ray diffraction and profil-matching refinements. Solid state nuclear magnetic resonance, Fourier transforms infrared and Raman spectroscopies with scanning electron microscopy were used to describe the microstructure and chemical composition of the as-prepared ceramics. It was found that solid solutions in the range 0 < x ≤ 0.1 are structurally similar to the zircon structure of YVO₄. The luminescence properties of Eu³⁺ doped samples were investigated. Under excitation of 398 nm, the Li_xY_1-yEu_y(VO₄)_1-xF_4x (x = 0.05, 0.07, 0.1; y = 0.05, 0.10, 0.15, 0.20) solid solution exhibited red emission originating from the strongest ⁵D₀→⁷F₂ transition. As the amount of Li⁺ and F^- contents increases, the photoluminescence efficiency improved. So, the solid solution ceramics can be considered promising red phosphors for light-emitting diodes.
