摘要：

This paper reports that the high pressure in situ angle dispersive x-ray diffraction and Raman scattering studies on CoPt and NiPt hollow nanospheres are performed by means of a diamond anvil cell for generating external pressure at room temperature.The crystal structures of both the CoPt and NiP hollow nanospheres keep stable up to about 41 GPa.Moreover,it shows that the hollow nanospheres possess higher bulk moduli than their bulk counterparts by using the frst-principles density functional theory.
