| 英文摘要 | The high-pressure behavior of zircon structured YPO4 (with/without Eu3+ doping) nanoparticles was examined at room temperature using in situ synchrotron X-ray diffraction (XRD) and photoluminescence (PL) measurements. In contrast with the reported XRD results of bulk YPO, upon compression, the nanoparticles showed a distinct transition sequence: zircon phase -> scheelite phase (similar to 18 GPa) without the metastable monazite phase. By the return to ambient pressure, both XRD and PL results revealed that the scheelite phase could be reserved. Further Raman experiments helped us to identify the valuable mode nu(1)(A(g)) of the scheelite structure in the quenched samples. The dopants effect, quasi hydrostatic stress, and nanoscale-induced surface energy difference are considered to explain the high-pressure behavior of the nanoparticles. It is proposed that the nanoscale-induced higher surface energy contribution plays a crucial role in the distinctive high-pressure behavior of the nanoparticles. |
