Abstract

This project aims to obtain heavy metal oxides based glasses doped with transition metal salts (Mn, Fe, Ag, Ni, Au). The Glass compositions will be prepared by the melting-quenching technique. The project also aims the preparation and characterization of glass-ceramics by controlled heat treatment of the glasses in a temperature above the glass transition. To study the thermal, structural, optical and magnetic properties of the glasses and glass-ceramics, the samples will be analyzed by thermal analysis (DSC), UV-Vis and Raman spectroscopy, electron paramagnetic resonance (EPR), and magnetic measurements will be done with a vibrating sample magnetometer (VSM). To verify the presence of nanoparticles, transmission electron microscopy (TEM) will be used. The characterization of the nanoparticles can also be performed using chemical analysis (EDX) and X-ray diffraction.
