Outline
In situ energy dispersive X-ray diffraction measurements on nano zinc sulfide shell have been carried out by using diamond anvil cell with synchrotron radiation. The highest pressure is 33.3 GPa in the experiment. The raw materials contain two structures of ZnS, which are wurtzite and zinc blende respectively. With increasing pressure, the wurtzite structre was transformed to zinc blende structure at 11.2 GPa. A phase transition from zinc blende structure to rocksalt structure occurred as the pressure reached to 16.0 GPa. Two unknown diffraction peaks were found in the range of pressure from 17.5 GPa to 21.0 GPa. The rocksalt structure existed as the pressure reached to 33.3 GPa. Both of the phase transitions are reversible.
