Role of WO3 on the conductivity, Judd-Ofelt and luminescence properties of 20K2O−xWO3−(78−x)TeO2−1Er2O3−1Yb2O3 glass system

Role of WO3 on the conductivity, Judd-Ofelt and luminescence properties of 20K2O−xWO3−(78−x)TeO2−1Er2O3−1Yb2O3 glass system

Glasses with the composition of 20K2O−xWO3−(78−x)TeO2−1Er2O3−1Yb2O3 (x = 0–9 mol%) were prepared using the melt-quenching method. Tellurite-based glasses exhibit low phonon energy and when combined with high-density heavy-metal oxides like WO3, they show potentially promising applications in photoni...

Glasses with the composition of 20K2O−xWO3−(78−x)TeO2−1Er2O3−1Yb2O3 (x = 0–9 mol%) were prepared using the melt-quenching method. Tellurite-based glasses exhibit low phonon energy and when combined with high-density heavy-metal oxides like WO3, they show potentially promising applications in photonic devices. Therefore, this study aims to investigate the impact of WO3 on structural, DC conductivity, optical, and photoluminescence properties using FTIR, impedance, UV–Vis, and photoluminescence spectroscopies of the present glass system. The results revealed non-linear variations in non-bridging oxygens and optical band gaps, with DC conductivity reaching a maximum at 5 mol% WO3. Judd-Ofelt analysis indicated increased oscillator strength and Ω2 with a decrease at 5 mol%, attributed to enhanced multiphonon relaxation affecting Er3+ site asymmetry. Photoluminescence measurements revealed enhanced green (524 nm, 547 nm) and red (655 nm) emissions with maximum intensity observed at 7 mol% WO3, suggesting that these glasses are promising candidates for use in optical amplifiers and lasers. © 2024 Elsevier Ltd and Techna Group S.r.l.
