“…In the low range of 2theta angle (5 • to 16 • ), one can also observe an increased background intensity due to more efficient X-ray scattering in air. Obtained X-ray patterns are similar to those that can be find in literature [31][32][33]. The results of DSC analysis are presented in Figure 1b.…”

The phosphate glass samples doped with Tb2O3 oxide (general formula: P2O5-Al2O3-Na2O-Tb2O3) were synthesized and studied for usage in high-dose radiation dosimetry (for example, in high-activity nuclear waste disposals). The influence of terbium concentration on thermoluminescent (TL) signals was analyzed. TL properties of glasses were investigated using various experimental techniques such as direct measurements of TL response vs. radiation dose, Tmax–Tstop and VHR (various heating rate) methods, and glow curve deconvolution analysis. The thermoluminescence dosimetry (TLD) technique was used as the main investigation tool to study detectors’ dose responses. It has been proved that increasing the concentration of terbium oxide in glass matrices significantly increases the thermoluminescence yield of examined material. For the highest dose range (up to 35 kGy), the dependence of the integrated thermoluminescent signals vs. dose can be considered as a saturation-type curve. Additional preheating of samples improves linearity of signal vs. dose dependencies and leads to a decrease of the signal loss over time. All obtained data suggest that investigated material can be used in high-dose radiation dosimetry. Additional advantages of the investigated dosimetric system are its potential ability to re-use the same dosimeters multiple times and the fact that reading dosimeters only requires usage of a basic TL reader without any modifications.

“…The rate of quenching is another factor that affects glass formation, the faster the rate of melt quenching, the better the glass formation. Lithium borate glass using the composition 30Li 2 O−70B 2 O 3 :Dy 2 O 3, cerium (Ce)‐doped strontium aluminium borates (SAB:Ce) with composition (50B 2 O 3 ‐15Al 2 O 3 −35SrO‐xCeO 2 ), silicon (Si)‐doped aluminium phosphate glass system for the ultraviolet (UV) range with the composition in molar percentage as 15Al 2 O 3 −35P 2 O5‐25CaO‐25Na 2 CO 3 (APCN), and zinc lithium borates (ZLB) doped with copper and sodium ions have been synthesized using the melt quenching method.…”

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.

“…TL response linearity of a TL dosimeter would ideally be linear over different doses, and would be beneficial for many applications such as dosimetry [32–35]. TL dose–response linearity was be studied using the linearity of index f (D) that is described as follows:

f\ (D)=\frac{TL\ (D)/D}{TL\ \left({D}_1\right)/{D}_1}

where TL (D) is the normalized measured signal as a function of dose D and TL (D 1 ) is the signal recorded at a low dose, D 1 .…”

In this work, different ion co‐doped Mg1‐xAl2O4 nanophosphors, coded as M5Cr‐5LaA, M5Cr‐5CuA, M0.07Si‐0.03CeA, and M0.05Ti‐0.05LaA, where 5Cr‐5La, 5Cr‐5Cu, 0.07Si‐0.03Ce, and 0.05Ti‐0.05La representing the added ions (mol%), were prepared using the sol–gel method. Phase structure, transmission electron microscope (TEM) images, and element feasibility were checked using X‐ray diffraction, TEM analysis, and energy dispersive X‐ray (EDX) spectroscopy. Their thermoluminescence (TL) response was checked using a 5 Gy γ‐test dose. The M0.05Ti‐0.05LaA sample was found to be best for the TL response with an ~1.1 times response compared with that of the MTS‐700 commercial detector. A wide range of dose–responses for the M0.05Ti‐0.05LaA sample was found up to a 20 Gy γ‐dose with the lowest detectable dose of ⁓23 μGy. Photon attenuation parameter results were Zeff ⁓10, which mean that the M0.05Ti‐0.05LaA sample could be considered as a near tissue equivalent material. Due to this study, the M0.05Ti‐0.05LaA sample can be considered as a promising detector for application in personal and medical dosimetric monitoring.
