Abstract Neodymium doped sodium strontium borate ( Nd 3 + : NaSrB ) glass system has been synthesized using conventional melt quenching technique. X-ray diffraction (XRD), Fourier-transform infrared (FT-IR) spectroscopy, Diffused reflectance spectro-scopy (DRS) and Thermoluminescence (TL) characterization have been done to observe the effect of neodymium oxide concentration on physical, optical and dosimetric properties of the prepared glass system. XRD pattern exhibit two broad humps and the close analysis revealed the presence of rare-earth induced nano-cristoballite. FT-IR spectra have been deconvoluted to study the presence of different structural groups. Band-gap ( E g ) has been calculated using the Kubelka-Munk method and is found to be sensitive to Nd 2 O 3 concentration. Maximum TL intensity is obtained for the 0.2 mol% concentration of rare-earth oxide and the shift in the peak towards lower temperature with the inclusion of Nd 2 O 3 indicates the formation of low-level traps. Our results suggest that, due to high TL efficiency, the glass sample with 0.2 mol% concentration of Nd 2 O 3 is suitable for the dosimetric applications.

NaSrB:Nd3+ 玻璃系统的合成，用于分析结构、光学和热致发光特性

摘要 利用常规熔体淬火技术合成了掺钕硼酸锶钠 (Nd 3 + : NaSrB ) 玻璃体系。已经完成 X 射线衍射 (XRD)、傅里叶变换红外 (FT-IR) 光谱、漫反射光谱 (DRS) 和热释光 (TL) 表征以观察氧化钕浓度对物理、光学和剂量学的影响制备的玻璃体系的性质。XRD 图案显示出两个宽峰，仔细分析表明存在稀土诱导的纳米方石英。FT-IR 光谱已被解卷积以研究不同结构基团的存在。带隙 (E g ) 已使用 Kubelka-Munk 方法计算得出，并且发现它对 Nd 2 O 3 浓度很敏感。为 0 获得最大 TL 强度。稀土氧化物的 2 mol% 浓度和峰向较低温度的移动以及包含 Nd 2 O 3 表明形成了低能级陷阱。我们的结果表明，由于高 TL 效率，具有 0.2 mol% Nd 2 O 3 浓度的玻璃样品适用于剂量测定应用。
