Influence of Pr6O11 Concentration on the Thermal, Structural, Physical, and Optical Behavior of SNW Glass Systems

Praseodymium‐doped antimony–phosphate glasses with the composition 47.5Sb2O3–47.5NaPO3–5WO3–xPr6O11 (x = 0.05, 0.1, 0.25, 0.3 mol%) were synthesized by melt‐quenching and characterized by DSC, FTIR, density, hardness, ultrasonic, and UV–Vis techniques. Tg (314.26°C–320.61°C) and ΔT (40.12°C–59.07°C) showed limited vari...

Novel Er3+/Nd3+-doped borofluoride glass materials for NIR optical fiber applications with suitable thermal and mechanical properties

To advance the performance of broadband optical fiber communication systems, a novel borofluoride-based glass system with the composition 60B2O3-20Pb3O4-10MgF2-10LiF (BPML) was synthesized and accordingly investigated. The base glass was doped with 1 mol% of Er3+, Nd3+, or their combination to produce BPML: RE3+ glass...

Role of free volume in governing electrical transport in V2O5–Cu2O–P2O5 glass ceramic nanocomposites

Glass–ceramic nanocomposites of xV₂O₅–(40−x)Cu₂O–60P₂O₅ (x = 10–40 mol%) were prepared by melt quenching followed by heat treatment at 873 K. XRD analysis confirmed the formation of Cu₂O and V₂O₅ nanocrystalline phases with crystallite sizes in the range of 16–27 nm embedded within a partially amorphous matrix. DC elec...
