Alkali‐borosilicate glass samples doped with 0.04‐0.7 mol % of neodymium oxide (20SiO 2 ‐(50‐x) H 3 BO 3 ‐20Na 2 CO 3 ‐10ZnO‐ xN d 2 O 3 ) 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.
