Abstract/OtherAbstract:
We demonstrate that the structural transition of ZnS nanoparticles from sphalerite to wurtzite is influenced by high pressures and temperatures. Under the pressure of 1 GPa, the structural transition of ZnS nanoparticles commences at 250 degrees C, much lower than that 400-500 degrees C for ZnS nanoparticles under normal pressures. With the increase of the annealing temperature, the transition is enhanced then inhibited with a maximum transition fraction of 14% at 300 degrees C and disappears at 500 degrees C. At the annealing temperature of 300 degrees C, the structural transition of ZnS nanoparticles keeps almost invariable with the increase of the pressure from 0.6 GPa to 1 GPa. The mechanism for the phenomenon is discussed.
