The visible electromagnetic resonances of Si/SiO2 core-shell nanoparticles are controlled by thermal oxidation. The core-shell nanoparticles comprising silicon and silicon dioxide are fabricated through laser ablation and thermal oxidation. The resonant wavelengths of magnetic and electric dipoles excited in the particles are experimentally demonstrated to be controlled in the visible region by the variation of the core diameter, through thermal oxidation.
