Solid state synthesis and photoluminescence of Sr3Y(PxV1-xO4)3: Eu3+ submicrocrystalline rod

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 -aEuro parts per thousand x O-4)(3): Eu3 + (x = 0 center dot 1, 0 center dot 3, 0 center dot 5, 0 center dot 7, 0 center dot 9) phosphors has been synthesized. These phosphors present the column-like particles with a width of 250 nm and a length of 1 mu 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 center dot 3V0 center dot 7O4)(3) has been shown to be the best composition among different compositions. Furthermore, the concentration quenching of Eu3 + in Sr3Y(P0 center dot 3V0 center dot 7O4)(3) took place and the optimum concentration of Eu3 + is 5 mol % in the range of 1-9 mol %.
