Physical and structure properties of QS-P2O5-CaO-BaO-Gd2O3/GdF3 glasses medium doped with europium (III)

ABSTRAK

Optical glass media derived from native natural resources, specifically Huta Ginjang (HG) quartz sand, were synthesized using a melt-quenching technique at 1200°C. The chemical composition of the glass matrix adhered to the formulations 15QS + 57 P2O5 + 15 CaO + 5 BaO + 5 Gd2O3 + 3 Eu2O3 and 15QS + 57 P2O5 + 15 CaO + 5 BaO + 5 GdF3 + 3 Eu2O3. Each sample was doped with active Europium (Eu3+) ions at a concentration of 3 mol%, thus creating a difference between the two samples based on the incorporation of Gd2O3 (PCBGO) with GdF3 (PCBGEF). The formed samples were then cut and polished to achieve optimal dimensions and transparency. Various physical characteristics, including density, ion concentration, and overall molar volume, were assessed using Archimedes' principle in addition to numerical calculations. In contrast, the structural properties were evaluated through fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) techniques to elucidate the functional groups present in the structure and diffraction patterns exhibited by the samples. The results of this study were conducted to contribute to the advancement of silica-phosphate glass materials intended for optical medium amplifiers using rare earth ions.
