Thermoluminescence (TL) materials exhibit a wide range of applications in different areas such as personal dosimetry, environmental dosimetry, medical research etc.Doping of different rare earth impurities in different hosts is responsible for changing the properties of materials useful for various applications in different fields. These materials can be irradiated by different types of beams such as γ-rays, X-rays, electrons, neutrons etc. Various radiation regimes, as well as their dose-response range, play an important role in thermoluminescence dosimetry. Several TL materials, such as glass, microcrystalline, nanostructured inorganic materials and recently developed materials, are reviewed and described in this article.

“…This tendency of increased crystallite size due to high-temperature heat treatments is observed in other materials, as already reported for ZnO (Soares et al, 2017), BeO (Altunal et al, 2020) and TiO2 (Lukong; Ukoba; Jen, 2022). One feasible reason for this is that more energy is being supplied to the system, which results in rearrangements in the lattice, either by getting longer interatomic distances or the creation of defects.…”

“…Moreover, TL and OSL are powerful techniques for analysing materials beyond their application in dosimetry, hence, it has stimulated research in new materials, as well as a more in-depth comprehension of the underlying mechanisms. Just for a matter of exemplification, one might cite that the potential application of zinc oxide (ZnO) as a dosimeter has been reported (Cañes-Morales et al, 2023;Soares et al, 2017), as is also the case for strontium aluminate-based materials (Tatumi et al, 2019;Zúñiga-Rivera et al, 2014). Finally, investigations combining both microstructural and luminescence characterisation have been successfully reported for different materials, as is the case of magnesium aluminate and borates (Ozdemir et al, 2021;Pan et al, 2021).…”

thing, gave me suggestions and advice, or opened their laboratories to me, and of course, people who are also friends and who made this journey easier. I hope I have not missed anyone here.As of now, thanks so much to you all.Firstly, I want to thank God and my family (my parents Cicero and Ivanilda, and my sister Soraia) for the immeasurable support. The certainty I have of you being there is by itself a comfort. I was always encouraged that education is a powerful tool, and no one can take it from me.My academic path would have been neither enjoyable nor successful if I did not have an advisor who is not just a scientific example, but also a friend. So, special thanks to Professor Dr Sonia Tatumi, whom I have known for more than eight years now, and who has an experience that she is always willing to pass on. Thank you for your endless patience, the wise advice, the incentive by saying "vai dar certo!" when I might have thought something would not work, and for pushing me forward to get the best.Vielen Dank Dr Clemens Woda, for kindly hosting me at the Institute of Radiation Medicine of the Helmholtz Zentrum München for one year. Your expertise enriched this work. An extended acknowledgement to the other researchers of the group in Munich, Dr Markus, Dr Janine, and Dr Kaiser. Moreover, a special thanks to Alessia Mafodda and Elif Kara, for their friendship.Thanks to Laurence Taylor, my partner, for your company and confidence in me, even in the harsh moments. Your support motivates me to seek the best.To the people from the laboratory of dosimetry and dating (LDD) of the Federal University of São Paulo (UNIFESP), where I started to understand what it means to do research.
