Using rare earth coordination polymers with ortho-hydroxylbenzoic acids as rare earth species and composing with organic polymers as the hybrid precursors, Sr3Y(P𝑥V1−𝑥O4)3: Eu3+ (𝑥 = 0.1, 0.3, 0.5, 0.7, 0.9) phosphors has been synthesized. These phosphors present the column-like particles with a width of 250 nm and a length of 1 𝜇m. The value of red emission to orange emission for Eu3+ varies with the V content, indicating that the RO (red/orange) value increases with the increase of V content due to the lower electronegativity of V. Sr3Y(P0.3V0.7O4)3 has been shown to be the best composition among different compositions. Furthermore, the concentration quenching of Eu3+ in Sr3Y(P0.3V0.7O4)3 took place and the optimum concentration of Eu3+ is 5 mol % in the range of 1–9 mol %.
