英文摘要Nanophase materials have novel physical and chemical properties, differing from bulk materials. It is of exceptional interest to investigate the size effect on structural stability in nanocrystals. Here, we investigated pressure-induced phase transitions in nanosized Er2O3 using angle-dispersive synchrotron X-ray diffraction up to 40.6GPa. Nano-Er2O3 has enhanced transition pressure and higher bulk modulus (K-0) than its bulk counterparts. Amorphous Er2O3 nanoclusters with traces of monoclinic phase are obtained upon compression. This is the first time that partial amorphous structure under compression was observed in nano-Er2O3, indicating a kinetic trapping of partial amorphous Er2O3 on pressurizing.
