In-situ energy dispersive X-ray diffraction (EDXD) on ZnS nanocrystalline was carried out under high pressure by using a diamond anvil cell (DAC). Phase transition of nano ZnS from wurtzite to rocksalt occurred at 16.0 GPa and 16.7 GPa for 10 nm and 3 nm sample, respectively, which were higher than that of the bulk materials. The structures of ZnS nanocrystalline at different pressures are built by using Materials Studio (MS) and the bulk modulus and the pressure derivative of ZnS nanocrystalline were derived by fitting the equation of Birch-Murnaghan. The resulting modulus was higher than that of the corresponding bulk material, indicating that nanomaterial possesses higher hardness than its bulk materials.
