Simulations based on thermal spike model. (a) Schematic model for the thermal simulation of a Ni particle embedded in the SiO2 matrix irradiated by 120 MeV Au+9 ion. (b) Calculated radial profile of lattice temperature in the z = 0 plane of bulk SiO2 and seven different spherical Ni nanoparticles (2, 4, 6, 10, 15, 20, 30 nm) embedded in silica after 1 ps and (c) 10 ps of ion impact. The melting (T M) and vaporization (T V) temperature of SiO2 and Ni are also indicated
