“…The addition of sodium oxide (Na 2 O) to a host glass can increase the glass transition temperature (Tg), eventually leading to higher thermal stability [17]. Moreover, Na 2 O is added to increase homogenization, to reduce the melting point of the glass host, and to reduce the glass damage and bubbles [18,19].…”

“…Analyses of dose distribution: Examining dose distribution to determine the paleo dose is an essential supplementary concern about the radiation dose acquired during burial. A few tens of aliquots were measured using the single aliquot SAR technique, and it is advised that the accurate paleo dose be chosen from this range (Balu et al, 2016). The mean value of the paleo dose values will be overestimated if the grains were sparsely bleached during transit and deposition, causing the dose distribution to be right skewed (Murari, 2007).…”

Thermoluminescence dosimeters (TLDs) are widely used in radiation dosimetry due to their excellent properties, such as high sensitivity, small size, and ability to measure low doses of radiation. This review focuses on the structural properties of TLD materials, as well as their preparation, application, and adaptability. The review covers the various types of TLD materials, crystal structure, and properties, including energy response and fading characteristics. The different methods used to prepare TLD materials, such as solid-state synthesis, sol-gel synthesis, and solution growth methods, are discussed in detail. The review also includes a detailed discussion of the various applications of TLDs, including medical, environmental, and industrial radiation dosimetry. Extensive information on TLD is reviewed, and the TL characteristics that have a noticeable impact on the TL dosimetry potential for human and other purpose utilisation, such as mineral, oil, and gas resource investigation, can be done using natural and artificial TL signals. Information on TL measurement process requirements and the TL characteristics that have a noticeable impact on a compound TL dosimetry potential are also addressed. Finally, the review concludes by highlighting the adaptability of TLD materials to different dosimetry applications and their potential use in the future.

“…Zinc ions behave like any other typical alkali oxides octahedrally coordinated when acting as a network modifier. As the former, ZnO enters the network with ZnO4 structural units (Balu et al, 2016). As Balu et al, 2016 described, ZnO plays a dual role in zinc borate glasses.…”

This study explores the properties of Al-Li-Zn glass doped with Dy3 + as a potential radiation dosimeter. The glass was prepared using the quenching technique, and various characterisations were performed to evaluate its properties. X-ray diffraction (XRD) analysis was utilised to identify any crystalline or amorphous phases in the glass. The results indicated the formation of amorphous, as supported by the absence of XRD peaks. UV-vis spectroscopy was employed to examine the optical properties of the glass. It revealed a noticeable absorption peak in the visible region, characteristic of the Dy3 + ions. PL spectra luminous peaks at 348 nm (yellow), 529 nm (green), and 625 nm (orange hue), which corresponded to the 4H15/2 → 6P7/2, 4F9/2 → 6H15/2, 4F9/2 → 6H15/2, and 4F9/2 → 6H13/2 transitions in 1.5 and 2.5 Dy3 + respectively. Significant decrease in \({\text{T}}_{\text{g}}\)from 257°C in the undoped sample to 101°C in the doped sample, Tm of the doped sample dropped from 862°C to 815°C and Tc of the doped sample dropped from 756°C to 444°C, suggesting a reduced crystallisation threshold. FTIR analysis demonstrated that OH groups displayed peaks within the 2200 to 4000 cm range. Stretching vibrations of BO3 units occurred between 1200 and 1600. Stretching vibrations of BO4 units were observed between 800 and 1200. The results indicate that when Dy3 + ions and zinc oxide are added, the arrangement of the glass structure is altered, causing a transformation from B03 groups to B04 groups. This transformation leads to defects in a stable trap environment suitable for thermoluminescence phenomena. Considering its properties and optical characteristics, the samples with 1.5 and 2.5 mol % of Dy3 + showed remarkable thermoluminescence properties, suggesting a suitable use as a dosimeter to gauge radiation exposure. The glass demonstrates stability and absorption capability, making it worth considering for radiation detection applications.
