研究目的
Investigating the structural, optical, and thermoluminescence properties of Er3+-doped sodium–strontium–borate glasses for potential application in radiation dosimetry.
研究成果
The Er3+-doped NaSrB glasses exhibit promising properties for radiation dosimetry applications, including suitable Zeff values close to human soft tissue. The study confirms the amorphous nature, structural changes with doping, and sensitivity of optical band gap to dopant concentration.
研究不足
The study focuses on a specific range of Er3+ concentrations and may not cover all potential variations in properties at higher or lower concentrations. The hygroscopic nature of borate glasses could also affect long-term stability.
1：Experimental Design and Method Selection
The study employed conventional melt quenching technique for glass synthesis, XRD for confirming amorphous nature, FTIR for structural analysis, and TL for thermoluminescence properties.
2：Sample Selection and Data Sources
Glass series (70 ? x)B2O3 ? 20Na2O ?10SrO ? xEr2O3 was synthesized with x varying as 0.0, 0.2, 0.4, 0.6, 0.8 and 1.0 mol%. Analytical reagent-grade oxides were used.
3：List of Experimental Equipment and Materials
Electronic balance, agate mortar, silica crucible, electric muffle furnace, graphite mold, electric furnace, Rigaku miniflex 600 pro-powder X-ray diffractometer, Hitachi U-3900H UV–Vis double-beam spectrometer, Intech TLD reader, model (I-1501 DC), Gamma chamber GC-1200.
4：Experimental Procedures and Operational Workflow
Oxides were weighed, mixed, melted, quenched, annealed, and cooled. XRD, FTIR, and TL measurements were conducted following specific protocols.
5：Data Analysis Methods
Kubelka–Munk method for band gap calculation, Chen’s peak shape method for kinetic parameters, and calculations for physical parameters like density, molar volume, etc.
