Abstract |
|
|
| The structure and thermoluminescence (TL) characteristics of the newly prepared La2O3 doped boro-phosphate glass were explored. La2O3 was added in 0.7 mol. % concentration to the glass structure. A reasonable response was obtained with an abroad peak contained at about 194 ºC. X-ray diffraction (XRD) was used to characterize the prepared sample. Deconvolution was made to obtain the other dosimetric characteristics; trap parameters, using the PeakFit program. Four peaks were obtained from the deconvolution at about 150,169, 183, and 195 ºC. The activation energy was calculated and found to range between 0.788 - 1.45 eV for the deconvoluted peaks. In addition, the frequency factor (s) was estimated and found to be 4.07x1015 -6.095x107 s-1. The obtained results showed reasonable TL- characteristics of the prepared samples. |
