“…This reduction in the TL response might be due to the well‐known concentration quenching effect. This effect has been first described by Johnson and Williams, and recently developed and presented by several models . Based on the role of the Nd as a TL activator atom and its concentration, the phenomenon of concentration quenching can be explained.…”

“…This effect has been first described by Johnson and Williams, 21,22 and recently developed and presented by several models. 23,24 Based on the role of the Nd as a TL activator atom and its concentration, the phenomenon of concentration quenching can be explained. In order to be an effective emission center, the activator atom should be existed within a minimum free lattice space without any existence of another activator atom of the same type around it.…”

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.

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.
