“…It should be noted that the intensity of the thermoluminescence signal and the shape of the glow curve depend on the sample heating rate. As mentioned before, there is a different TL response of the as-made glass and glassceramics [51,114]. Figure 6 shows the influence of heat treatment on the intensity of TL signal and temperature of the glow peak.…”

“…That explains why, after lithium oxide addition to borate matrix, boron-oxygen triangle attaches an additional oxygen atom forming boron-oxygen tetrahedron. The oxyfluoride glasses from the LiF-B2O3-SiO2 system are characterized by favorable thermoluminescent properties [51]. The increase in lithium fluoride The incorporation of alkali ions in the borate network can reduce the risk of different phases formation in the glass by converting BO 3 triangle borate units to BO 4 tetrahedra [49].…”

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.
