“…Low heating rate gives a wide opportunity to the electrons in the traps to completely evacuate, producing the low‐temperature glow curve. High heating rates, around 5‐20°C/s, on the other hand, the traps release their electrons quicker and hence glow curves quickly formed, shifting their peaks to high temperatures …”

“…1 Borate glasses doped with alkali metal ions and/or rare earths have been extensively studied as thermoluminescence dosimetric materials; because they have several dosimetric properties compared with the other glass dosimeters. [2][3][4][5][6][7][8][9] A borate glass-with minute amounts of impurities that are typically existent in most samples-is experienced to a formation of electron-hole pairs, as well as trapping charge carriers at the defect centers of the sample upon exposure to ionizing radiation. Up to the moment, researchers have extensively discussed the different mechanisms of luminescence in borate glasses.…”

Alkali‐borosilicate glass samples doped with 0.04‐0.7 mol % of neodymium oxide (20SiO2‐(50‐x) H3BO3‐20Na2CO3‐10ZnO‐xNd2O3) have been prepared by the melt quenching method. Thermoluminescence (TL) properties such as: dose–response, thermal fading, minimum detectable dose, and reproducibility of the gamma irradiated samples were investigated. Kinetic and trapping parameters such as trap depth, kinetic order, and frequency factor were studied by using the glow curve shape, initial rise and computerized glow curve de‐convolution (GCDC) methods. Among the studied concentrations, the obtained results showed that alkali‐borosilicate glass doped with 0.15 mol % neodymium oxide is the most sensitive one. This glass composition has a good linear TL gamma dose–response over a wide dose range of 0.5‐1000 Gy, as well as low fading and excellent reproducibility. These obtained features recommend the new prepared glass for many radiation detection applications.

“…The dosimetric properties of borate glass with different activators have been studied extensively. [ 4–8 ] These activators or impurities play an important role in the creation of electron–hole traps. Adding silica to the borate glass stimulates them to generate nonbridging oxygen hole centres (NBOHCs) after irradiation with high electromagnetic radiation energy such as X‐rays, gamma rays, or ultraviolet radiation.…”

Lithium borosilicate glass composite (SiO2–Li2CO3–H3BO3) doped with various concentrations of Sm2O3 (0–0.7 mole %) was prepared using the melt quenching method. The investigated thermoluminescence (TL) characteristics of the prepared system revealed that the highest TL response was obtained for this glass composite at 0.05 mol% Sm2O3. In this study, the 0.05 mol% Sm2O3‐doped lithium borosilicate glass composite was subjected to detailed dosimetric investigation in terms of its annealing condition, dose–response, and minimum detectable dose. The reproducibility of the response, thermal characteristics, and optical fading were also studied. The obtained results showed that the prepared glass composite had a linear dose–response over the wide gamma dose range 2Gy to 2 kGy, as well as reasonable thermal fading and excellent reproducibility. These attributes render the composite under investigation promising for utilization in radiation detection.

“…In fact, radiation‐induced luminescence phenomena related to the Cu + in Cu‐doped glasses have been widely investigated. However, many of these studies have focused on the thermoluminescence, optically stimulated luminescence, lyo—and mechano‐luminescence phenomena, or scintillation properties . Investigations of the RPL phenomena of Cu are very limited .…”

Radiophotoluminescence phenomenon in copper‐doped aluminoborosilicate glass

et al. 2018

Radiophotoluminescence phenomena have been widely investigated on various types of materials for dosimetry applications. We report that an aluminoborosilicate glass containing 0.005 mol% copper exhibits intense photoluminescence in the visible region induced by X‐ray and γ‐ray irradiation. The luminescence is assigned to the 3d94s1 → 3d10 transition of Cu+. The proportionality of the intensity of the induced photoluminescence to the irradiation dose was confirmed up to 0.5 kGy using 60Co γ‐ray irradiation. Based on the spectroscopic results, a potential mechanism was proposed for the enhancement of the photoluminescence. The exposure to the ionizing radiation generates electron‐hole pairs in the glass, and the electrons are subsequently captured by the Cu2+ ions, which are converted to Cu+ and emit the luminescence. For the glass containing 0.01 mol% copper, the pronounced enhancement of the photoluminescence was not observed because the reverse reaction, ie, the capture of the holes by the Cu+ ions, becomes prominent. The photoluminescence induced by the irradiation was stably observed for the glasses kept at room temperature and even for the glasses heat‐treated at 150°C. However, the induced photoluminescence could be eliminated by the heat treatment at a temperature at 500°C, and the glass returned to the initial pre‐irradiation state. The Cu‐doped aluminoborosilicate glass is a potential candidate for use in dosimetry applications.
