“…Garlick and Gibson in 1948 introduced RIR method to calculate the trap depth, turning out to be one of the best method for this matter . The initial rise method is based on the assumption that for T ≤ T M , and I ≤ I M , the TL intensity can be written as:

I = C \cdot exp (- E / k T)

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.

“…As only a small portion of TL glow curve is used, this method is very popular. This fairly applies to intensities smaller than 10%‐15% of the maximum intensity corresponding to a certain cut‐off temperature . The initial raise method is based on the assumption that for T ≤ T M , and I ≤ I M , the TL intensity can be written as:

I = const.

Up until this moment, there was no detailed study concerning the kinetic parameters of zinc-doped borosilicate glass thermoluminescent (TL) material. A significant TL peak was observed upon gamma irradiating the samples, at around 185°C. Evaluating activation energy (E), frequency factor (s), and order of kinetics (b) were conventionally obtained by peak shape (PS) method, repeated initial rise (RIR), and variable heating rate (VHR) methods. The obtained results indicated that the zinc-doped borosilicate glass glow curve after gamma irradiation is legitimately a superposition of seven interfered glow peaks. Therefore, we cannot use computerized glow curve deconvolution (CGCD) method alone in determining the kinetic parameters in this case. Additive dose (AD), repeated initial raise (RIR), and variable heating rate (VHR) methods together with computerized deconvolution (CGCD) method by using the TolAnal software have been applied to determine the kinetic parameters of zinc-borosilicate glass due to the existence of several nearby overlapped peaks. RIR method gives the value of AE 2.3% average variation, for the activation energies, compared with those obtained by GCDC. The obtained results clearly show the consequences reliability.

“…So the higher temperature T 2 is required for the same amount of thermal release to take place at b2. In this way the whole glow curve and hence the glow peak temperature shifts to right side as the heating rate increases in a manner depending on the half-life and the time spent at each temperature [36].…”
