We offer a critical assessment of the operational properties of MgB4O7:Ce,Li for OSL dosimetry, as reviewed in the literature and complemented by measurements of thermoluminescence spectroscopy, sensitivity, thermal stability, lifetime of the luminescence emission, dose response at high doses (&gt;1000 Gy), fading and bleachability. Overall, compared with Al2O3:C, for example, MgB4O7:Ce,Li shows a comparable OSL signal intensity following exposure to ionizing radiation, a higher saturation limit (ca 7000 Gy) and a shorter luminescence lifetime (31.5 ns). MgB4O7:Ce,Li is, however, not yet an optimum material for OSL dosimetry, as it exhibits anomalous fading and shallow traps. Further optimization is therefore needed, and possible avenues of investigation encompass gaining a better understanding of the roles of the synthesis route and dopants and of the nature of defects.<\/jats:p>","DOI":"10.3390\/ma16083051","type":"journal-article","created":{"date-parts":[[2023,4,13]],"date-time":"2023-04-13T02:09:21Z","timestamp":1681351761000},"page":"3051","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Addressing Current Challenges in OSL Dosimetry Using MgB4O7:Ce,Li: State of the Art, Limitations and Avenues of Research"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7355-1220","authenticated-orcid":false,"given":"Lily","family":"Bossin","sequence":"first","affiliation":[{"name":"Department of Radiation Safety and Security, Paul Scherrer Institute, Forschungsstrasse 111, 5232 Villigen, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1638-2771","authenticated-orcid":false,"given":"Igor","family":"Plokhikh","sequence":"additional","affiliation":[{"name":"Department of Radiation Safety and Security, Paul Scherrer Institute, Forschungsstrasse 111, 5232 Villigen, Switzerland"},{"name":"Laboratory for Multiscale Materials Experiments, Paul Scherrer Institute, Forschungsstrasse 111, 5232 Villigen, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6894-381X","authenticated-orcid":false,"given":"Jeppe Brage","family":"Christensen","sequence":"additional","affiliation":[{"name":"Department of Radiation Safety and Security, Paul Scherrer Institute, Forschungsstrasse 111, 5232 Villigen, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4460-7106","authenticated-orcid":false,"given":"Dariusz Jakub","family":"Gawryluk","sequence":"additional","affiliation":[{"name":"Laboratory for Multiscale Materials Experiments, Paul Scherrer Institute, Forschungsstrasse 111, 5232 Villigen, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5848-5299","authenticated-orcid":false,"given":"Yuuki","family":"Kitagawa","sequence":"additional","affiliation":[{"name":"National Institute of Advanced Industrial Science and Technology (AIST), Ikeda, Osaka 563-8577, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4576-1623","authenticated-orcid":false,"given":"Paul","family":"Leblans","sequence":"additional","affiliation":[{"name":"Radiology Division, Agfa NV, 2640 Mortsel, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7620-0119","authenticated-orcid":false,"given":"Setsuhisa","family":"Tanabe","sequence":"additional","affiliation":[{"name":"Graduate School of Human and Environmental Studies, Kyoto University, Kyoto 606-8501, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dirk","family":"Vandenbroucke","sequence":"additional","affiliation":[{"name":"Radiology Division, Agfa NV, 2640 Mortsel, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4615-6698","authenticated-orcid":false,"given":"Eduardo Gardenali","family":"Yukihara","sequence":"additional","affiliation":[{"name":"Department of Radiation Safety and Security, Paul Scherrer Institute, Forschungsstrasse 111, 5232 Villigen, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,12]]},"reference":[{"key":"ref_1","first-page":"1","article-title":"Luminescence dosimetry","volume":"2","author":"Yukihara","year":"2022","journal-title":"Nat.
