AbstractWe probed the high-pressure response of the YV1-xPxO4:Eu3+ (x = 0, 0.5, 0.7, 1.0) solid-solution nanoparticles using angular dispersive synchrotron X-ray diffraction (XRD) and Raman techniques at room temperature. In situ diffraction results showed that the overall nanoparticles underwent an irreversible zircon-to-scheelite structural transformation. The transition pressures were similar to 9.3, similar to 12.1, similar to 14, and similar to 18.4 GPa for the YV1-xPxO4:Eu3+ (x = 0, 0.5, 0.7, 1.0). samples, respectively. Coupled with the zircon-to-scheelite transition features, it was proposed that the transition pressure was probably governed by the stiffness of VO4/PO4 units in the solid solutions. This claim was verified by further Raman measurements, which revealed that the stiffness of VO4/PO4 units was enhanced with increasing P contents. The structural refinements showed that the samples with comparable particle size (20-90 nm) became less compressible with increasing P. content (x 0 -> 0.7 -> 1.0). However, the compressibility of the YV1-xPxO4:Eu3+ sample with smaller particle size (10-30 nm) was similar to that of the YV1-xPxO4:Eu3+ sample. The general compressibility behavior as a function of P content was ascribed to the special packing style related to the stiffness of VO4/PO4 tetrahedra in zircon structure, and the higher surface energy contribution was responsible for the exceptional compressibility in the smaller nanoparticles.
