Abstract
Using rare earth coordination polymers with ortho-hydroxylbenzoic acids as rare earth species and composing with organic polymers as the hybrid precursors, Sr3Y(P x V1 − x O4)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 μ m. 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 %.
