| The electronic structure and optical properties of metallic nanoshells are theoretically investigated. An efficient implementation of the Time Dependent Local Density Approximation creates the possibility of applying ab initio calculations to real size metallic nanoshells for which experimental data are available. It is proven that, when the dielectric effects of the core, embedding medium and d-electrons are taken into account, the ab initio calculations reproduce the experimentally measured photo-absorption cross section of these unique nanoparticles. |
