“…Previously [13], we had investigated the 10BaO-20ZnO-20LiF-(50-x)B 2 O 3 -xYb 2 O 3 (x = 0.1, 0.5, 0.7, and 1.0 mol%) glass system for TL dosimetry and obtained the highest integrated TL intensity at the 0.1 mol% doping level. The glass seemed to be suitable for food irradiation application in the dose range of 0.25 to 1 kGy, which was comparable to other rare-earth doped glasses like PbO-Al 2 O 3 -SiO 2 :Nd 3+ [14], Dy 3+ -doped lithium borate [16], and BaO-B 2 O 3 -P 2 O 5 -Al 2 O 3 -Tb 2 O 3 [15]. The glass showed quite high sensitivity, a threshold dose of 166 ± 3 Gy, and an effective atomic number of 9.7.…”

“…The fundamental methods for defect analysis in glasses have been density [3,7], optical absorption spectroscopy [8][9][10][11], Fourier transform infrared (FTIR) spectroscopy [9,11], and electron spin resonance (ESR) [1,2,12]. Advances in science have expanded the experimental approaches to some luminescence techniques like thermoluminescence (TL) [13][14][15][16], radiothermoluminescence (RTL) [10], and photoluminescence (PL) [17]. Every characterization technique has its significance in the analysis of resultant radiation-induced defects in the glass.…”

“…In the ZnO-Na 2 O-H 3 BO 3 -BaO glass system [25], not only the number of bonds per unit volume increased with BaO addition, but also the radiation attenuation characteristics improved and the glass durability was maintained until 15 mol% BaO content. The rare-earth ions can influence the mechanisms responsible for the formation of the radiation-induced color centers [10] and even change the TL features of the host [16]. The ytterbium rare-earth ion is commonly used in optical fiber and laser applications [26,27].…”

A Yb3+-doped borate glass system was examined for the structural and optical modifications after γ-irradiation. Among the studied 10BaO-20ZnO-20LiF-(50-x)B2O3-xYb2O3 (x = 0.1, 0.5, 0.7, and 1.0 mol%) glasses, the 10BaO-20ZnO-20LiF-49.9B2O3-0.1Yb2O3 glass showed the highest thermoluminescence intensity, trap density, and trap depth. The glass was irradiated with the optimum γ-dose of 1 kGy towards the analysis of radiation-induced defects. The amorphous nature was preserved before and after irradiation. The glass density slightly increased after irradiation. The structural rearrangement was evident from the Fourier transform infrared spectroscopy by the appearance and disappearance of some bonds after γ-irradiation. The transformation of [BO4] units into [BO3] units and non-bridging oxygens was deduced. The color of the glass darkened after irradiation and the optical absorption intensity enhanced between 250 and 700 nm. The optical bandgap reduced and Urbach energy increased upon γ-dose exposure. The electron spin resonance of the irradiated glass exhibited two signals at g = 2.0167 and g = 1.9938, corresponding to the non-bridging oxygen hole center and Boron E’-center, respectively.

“…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.

Investigation of thermoluminescence response and trapping parameters of natural barite samples from Dongargaon mine, India

et al. 2020

Dosimetry is a technique that quantitatively measures the ionizing radiation absorbed by matter. The present study was conducted on the barites from a mine at Dongargaon in Central India. Morphological and structural analysis of proposed sample was carried out using X‐ray diffraction and standard error of the mean. Thermal analysis and chemical composition of the proposed sample were carried out using thermogravimetric analysis and differential thermal analysis, and electron probe microanalysis. Thermoluminescence (TL) studies on a natural barite sample were performed using a Nucleonix TL1009I TL reader following sample irradiation with γ‐rays generated from a 60Co irradiation source. A broad TL glow curve was observed after TL study that was then deconvoluted using TLanal deconvolution software. Trapping parameters from the sample such as activation energy (E), order of kinetics (b), and frequency factor (s) were calculated using Chen’s peak shape method, the initial rise method, and Ilich’s method. The results indicated that the natural barite sample could be used in high‐dose TL dosimetric applications in various fields.
