The thermoluminescence properties and determination of trapping parameters of soda lime glass doped with erbium oxide

The thermoluminescence properties and trapping parameters of soda lime glass doped with erbium oxide (Er2O3) were investigated. The glow curve and linearity evaluations of the glass samples were carried out by irradiation with 100 kV of X-ray tube photon energy at a dose of 14 mGy. The results for the glow curve and linearity show that the S-2 glass sample is more suitable for using as a dosimeter. The lower detection limit (DLDL) of the S-2 glass samples was studied. Reproducibility of the S-2 glass samples was investigated by calculation of the detector variability index (DVI). Trapping parameters (activation energy and frequency factor) supported the results for the glow curve and fading of the glass samples. Physical properties of the glass samples were calculated. The results could explain the behavior of the modifier atoms when these were added into the network structures.
