摘要

The size effect on the high pressure phase transition of ZnO nanocrystals with grains from 18 up to 30 nm has been investigated. The phase transition from B4 (hexagonal wurtzite structure) to B1 (cubic rocksalt structure) was induced by high pressure and measured by energy-dispersive in situ synchrotron radiation powder diffraction in a diamond anvil cell under pressures up to 40 GPa at room temperature. It was found that the transition pressure of the B4 to B1 transformation in nanocrystalline ZnO is much higher than that in microcrystalline ZnO.
