Abstract
This study focused on the synthesis and physical properties of gadolinium silicate phosphate glass systems doped with dysprosium ions Dy3+ as potential optical materials. Glasses with varying dysprosium concentrations were prepared using a melt quenching method followed by annealing to achieve homogeneous and transparent samples. The chemical composition included quartz sand as the silica source combined with P2O5, CaO, BaO, Gd2O3, and Dy2O3. Physical characterization involved evaluating density, refractive index, and structural properties. The results showed that doping with dysprosium ions influenced the glass network structure and enhanced the materials potential for optical applications. The incorporation of rare earth ions like dysprosium into the gadolinium silicate phosphate glass matrix is promising for developing new optical reinforcement media with desirable luminescent and optical properties.
