Abstract The goal of the present project is to obtain glassy materials containing transition metal nanoparticles that will be studied in two fronts: The first concerns the preparation of glasses for photonics focusing mainly on the optical properties of heavy metal oxide glasses containing both nanoparticles and rare earth ions and their applications in all optical devices. The second one refers to the investigation of the energy transfer mechanism between metallic nanoparticles and rare earth with potential applications for optical amplifiers. Glasses will be prepared by the melting-quenching methodology. Transition metals, as well the rare earths ions, will be incorporated into the glass matrix during the melting process. Nanoparticles will be growth from the bulk by thermal treatment at temperatures to be determined. (AU) | |
