The present work proposes a preparation method for multilayered Au nanoparticle/silica/gadolinium compound/silica (Au/Si/Gd/Si) core-shell particles. Si-coated Au (Au/Si) core-shell particles with a size of 47.3 nm were prepared by a sol-gel reaction in the presence of the Au nanoparticles with a size of 16.9 nm prepared through a citrate-reduction method. Multilayered Au/silica/gadolinium compound (Au/Si/Gd) core-shell particles with a size of 55.0 nm were prepared by a homogeneous precipitation reaction in the presence of the Au/Si particles. The Au/Si/Gd/Si particles with a size of submicron meter were fabricated by the sol-gel reaction in the presence of the Au/Si/Gd particles
