【 摘 要 】

Using rare earth coordination polymers with ortho-hydroxylbenzoic acids as rare earth species and composing with organic polymers as the hybrid precursors, Sr₃Y(P_ð‘�?V_{1−ð�?��?}O₄)₃: Eu³⁺ (ð‘�? = 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(P_0.3V_0.7O₄)₃ has been shown to be the best composition among different compositions. Furthermore, the concentration quenching of Eu³⁺ in Sr₃Y(P_0.3V_0.7O₄)₃ took place and the optimum concentration of Eu³⁺ is 5 mol % in the range of 1â€�??9 mol %.
