Abstract

New rare earth-doped glasses with wide transparency and tunable optical properties show promise for various technological applications. While the effects of alkaline earth metals on glass compositions have been widely studied, their role in niobium-phosphate glasses remains unexplored. This study investigates Eu³⁺-doped niobium-lead pyrophosphate glasses modified with different alkaline earth metals, prepared via melt-quenching. Thermal, structural, optical, and spectroscopic properties were examined. Differential scanning calorimetry (DSC) showed that the thermal stability against crystallization decreased from Mg²⁺ to Ba²⁺, with Sr²⁺ exhibiting the lowest stability. Raman and solid-state NMR spectroscopy revealed minimal changes in the niobium-phosphate network but shifts in the Q⁰/Q¹ phosphate unit ratio were detected. Spectroscopic analysis showed that larger alkaline earth ions increase symmetry around Eu³⁺ and increase the ⁵D₀ lifetime. Sr²⁺-containing samples showed exceptional results, suggesting a possible substitution between Sr²⁺ and Pb²⁺ due to their similar ionic radii.

期刊介绍： Materials Research Bulletin is an international journal reporting high-impact research on processing-structure-property relationships in functional materials and nanomaterials with interesting electronic, magnetic, optical, thermal, mechanical or catalytic properties. Papers purely on thermodynamics or theoretical calculations (e.g., density functional theory) do not fall within the scope of the journal unless they also demonstrate a clear link to physical properties. Topics covered include functional materials (e.g., dielectrics, pyroelectrics, piezoelectrics, ferroelectrics, relaxors, thermoelectrics, etc.); electrochemistry and solid-state ionics (e.g., photovoltaics, batteries, sensors, and fuel cells); nanomaterials, graphene, and nanocomposites; luminescence and photocatalysis; crystal-structure and defect-structure analysis; novel electronics; non-crystalline solids; flexible electronics; protein-material interactions; and polymeric ion-exchange membranes.
