    Abstract
  • The R-p relationship of ZnO nanocrystals and bulk materials were determined by diamond anvil cell (DAC). Research results show that a phase transformation begins at the 7.9 GPa when the particle is 20 nm nanocrystals, whereas the phase transition of ZnO bulk materials at 5 GPa. The smaller particle has larger phase transition pressure, and transformation pressure of bulk materials determined by DAC is lower than that previously reported. The structural properties of ZnO were discussed, and the domain fracture of nanocrystals under pressure was investigated.
