In this paper metallodielectric nanocomposites, obtained by directional growth of glass fibers doped with silver nanospheres, indium tin oxide (ITO)/antimony tin oxide nanoparticles (ATO) and simultaneously doped silver nanoparticles and erbium ions have been investigated. The manufacturing method is based on doping glass with plasmonic nanoparticles in directional glass solidification process. Our approach is a new bottom-up method of fabricating 3D metallodielectric nanocomposites with plasmonic properties. It enables manufacturing of isotropic bulk materials with plasmon resonances from metallic and semiconducting nanoparticles as well as it enables obtaining of plasmonic materials simultaneously doped with other agents like a rare earth ions in 3-dimensional matrices. Description of novel bottom-up fabrication process together with structural/optical characterization results will be presented.
