英文摘要The structure and photoluminescence properties are investigated under high pressure and high temperature for pure orthorhombic and hexagonal euf3 nanocrystals. under hydrostatic compression, the hexagonal euf3 remains stable at pressures up to 26 gpa. under nonhydrostatic compression, a cyclic phase transition from hexagonal to orthorhombic and then back to hexagonal is observed for the first time. when loading uniaxial compression, the pure hexagonal euf3 partly transforms to orthorhombic at 70 mpa, then the orthorhombic euf3 transforms to hexagonal at about 3 gpa, and the transition is completed at about 10 gpa. the cyclic phase transition is also observed during the heating process; the hexagonal transforms to orthorhombic at 550 degrees c and then to hexagonal at 855 degrees c. the content phase diagrams are obtained under high pressure and at high temperature.
