In this work, we prepared Ca2BO3Cl with various amounts (0.1–1.0%) of Tm2O3 by conventional solid-state reaction and investigated the dosimeter properties. Scintillation peaks at 370, 455, 470, and 650 nm that were derived from the 4f→4f transition of Tm3+ appeared in the X-ray induced scintillation spectra, and the highest scintillation intensity was detected from the 0.5% Tm2O3-doped Ca2BO3Cl. Furthermore, the Tm2O3-doped Ca2BO3Cl exhibited a thermally-stimulated luminescence (TSL) with a main glow peak at 300 °C, and the fabricated Tm2O3-doped Ca2BO3Cl exhibited a linear response in the 0.1–1000 mGy range. In addition, the TSL spectra confirmed that a final luminescence process for the TSL was the 4f→4f transition of Tm3+. In addition to TSL, optically-stimulated luminescence that was attributable to the 4f→4f transition of Tm3+ was recorded under 520 nm light, and the lowest detectable limit was about 1 mGy.

“…Therefore, the performance of scintillators strongly affects that of radiation detectors. Various scintillators, such as films, (6) ceramics, (7)(8)(9)(10)(11)(12) glasses, (13)(14)(15)(16)(17)(18)(19)(20)(21)(22) single crystals, (23)(24)(25)(26)(27)(28)(29)(30)(31)(32) and nanoparticles, (33) have been investigated to date. Single crystal materials tend to show excellent properties and are widely used as scintillators.…”

Tm-doped Y 3 Al 5 O 12 (YAG) single crystals with different Tm concentrations (0.1, 0.5, 1.0, and 2.0%) were grown using the floating zone method. X-ray-induced scintillation spectra, scintillation decay curves, and γ-ray-induced pulse height spectra of the obtained Tm-doped YAG single crystals were investigated. All the samples showed emission peaks due to the 4f-4f transitions of Tm 3+ ions, and the decay times were around 40-20 μs under X-ray excitation. The 0.5% Tm-doped YAG sample showed the highest light yield under 662 keV γ-ray excitation among the samples. The optimal dopant concentration of Tm-doped YAG single crystals was confirmed to be 0.5%.

Passive dosimeters enabling accurate measurement of doses from gamma rays to visible light are necessary to ensure efficient utilization of electromagnetic radiation in numerous fields like medical diagnostics and industrial manufacturing. The specific requirements for dosimeters in terms of dosimetry range, sensitivity, accuracy, and stability for each application have led to the development of various dosimeters based on new materials and new mechanisms. Here, a comprehensive review of different types of dosimeters classified according to the response signal, namely electron paramagnetic resonance, electrical, and optical, is provided. This review starts with a general introduction to dosimetry, a classification of dosimeters, and an elucidation of the necessity of dosimeters in various ranges of the electromagnetic spectrum. This is followed by an overview of the fundamental requirements of dosimeters, an explanation of the general dosimetry procedure, and the dosimetric quantities. Emphasis is given to the working mechanism, the design concept, and applications of each type of dosimeter as well as their respective strengths and drawbacks. Challenges and prospects are presented at the end of the review. This review provides an insightful overview of the material‐mechanism‐characteristics‐application relationship of different types of dosimeters that hopefully can serve as inspiration for the development of new devices.
