“…Rare-earth (RE) doped glasses are characterized by promising physical and chemical properties, inclduing: higher thermal stability [90], greater chemical durability [91], superior hardness and elastic modulus than traditional glass network modified by cationic dopants [92]. In general, the rare-earth elements are considered as network modifiers of the glass structure [93,94].…”

Different types of ceramics and glass have been extensively investigated due to their application in brachytherapy, radiotherapy, nuclear medicine diagnosis, radioisotope power systems, radiation processing of food, geological and archaeological dating methods. This review collects the newest experimental results on the thermoluminescent (TL) properties of crystalline and glassy materials. The comparison of the physico-chemical properties shows that glassy materials could be a promising alternative for dosimetry purposes. Furthermore, the controlled process of crystallization can enhance the thermoluminescent properties of glasses. On the other hand, the article presents information on the ranges of the linear response to the dose of ionizing radiation and on the temperature positions of the thermoluminescent peaks depending on the doping concentration with rare-earth elements for crystalline and glassy materials. Additionally, the stability of dosimetric information storage (fading) and the optimal concentration of admixtures that cause the highest thermoluminescent response for a given type of the material are characterized. The influence of modifiers addition, i.e., rare-earth elements on the spectral properties of borate and phosphate glasses is described.

“…One of the approaches to optimizing the composition is through the replacement of one or more components with another, either partially or completely [13]. This can lead to changes in the glass structure, thermal stability, and luminescence properties, and such studies can provide valuable insights into the optimization of rare earth-doped glasses [14].…”

Tm2O3 doped tellurite-zinc-bismuth-sodium (TZBN) glass samples with varying compositions were prepared through melt quenching technique. The composition of these glass was 60 TeO2 - (30-x) ZnO - 5 Bi2O3 - 5 Na2O - x Tm2O3 with (x = 0.5; 1.0; 1.5; 2.0 and 2.5 mol%). We reported the result of a systematic study of the thermal properties of these glass by using differential thermal analysis (DTA). The thermal characteristics of these glass (glass transition, Tg, crystallization, Tc, and melting, Tm) increased significantly with Tm2O3 content and the glasses were more thermally stable (greater ΔT=Tc-Tg). The glass transition value slightly increased from 314 to 323 °C otherwise thermal stability ΔT changed from 112 to 131°C. The ratio of Tg/Tm values for TZBN doped Thulium glasses were about 0.558 to 0.589, indicated that these glasses possess good thermal stability. The Hruby parameter (Kg) with Tm3+ doped in this study improved glass-forming ability, which is desirable for various applications such as optical fibers drawing and sensors.
