“…This might be a result of the already present/generated defects by thermal neutrons irradiation. Similar TL glow curves, however, were observed in soda-lime glass substrates studied by Balogun et al [8] with only a slight shift in the peaks positions. Their glass material has a relatively similar composite structure (73 w/o SiO 2 , 3.5 w/o (K 2 O, Na 2 O), 9 w/o CaO, 4 w/o MgO, 0.2 w/o Al 2 O 3 ) to our materials.…”

This work describes the thermoluminescence (TL) response of silica-based materials irradiated with thermal neutrons. These materials have the compositions (mol %) (60 + x)SiO2–(30 − x)Na2O–5MgO–5Al2O3, where x = 0, 5, 10 and 15. The irradiation was carried out in the fluence range 1 × 1014 – 1 × 1017 neutron cm−2. These glassy materials gave two TL glow peaks at around 473 and 643 K. The intensity ratio of these peaks is found to vary with varying SiO2/Na2O ratios. The peak at 473 K is more prominent at the ratio SiO2/Na2O = 75/15, while the intensity of the other one at 643 K increases by decreasing the value of this ratio. The former peak is attributed to both ‘AlO4’ hole centres and non-bridging oxygen (NBO) ion centres induced by neutrons irradiation, while the latter one could be ascribed to (NBO) ion centres introduced by the network modifiers, Na+ ions. The TL response against the neutron beam fluences of the material having the ratio SiO2/Na2O = 75/15 is found to show sublinearity in the above-mentioned range of fluence (using the area under the curve method). The other features such as high sensitivity and simple glow curve structure might be good indicators for this material to be used as a dosimeter in several applications such as thermal neutrons or in food irradiation.

“…The phenomenon of TL is also found in quartz and silica glasses. A number of workers have reported on the existence of TL and the associated mechanism in these materials [3][4][5][6][7][8][9][10][11][12][13]. From the application point of few, there are several advantages in using glass materials in dosimetry of ionizing radiations.…”

“…Materials in thin film form have great attention mainly because of their singular properties, which may differ significantly from their bulk attributes making them attractive for a wide variety of applications [9]. In particular, TL properties of thin films have a wide spectrum of potential applications in dosimetry for nonionizing radiation [10,11]. The interest to study the TL response of thin films has been motivated for their importance in the measurements of absorbed doses from weakly penetrating radiation to highly energetic radiation.…”
