Influences of dysprosium and phosphorous oxides co-doping on thermoluminescence features and kinetic parameters of lithium magnesium borate glass

This paper presents the main dosimetric characteristics and kinetic parameters of a newly proposed borate glass dosimeter modified with lithium and magnesium oxide (LMB) and co-doped with Dy 2 O 3 and P 2 O 5 . Dosimetric features include thermoluminescence (TL) glow-curve, annealing procedure, TL sensitivity, photon dose response, fading, reproducibility, minimum detectable dose, kinetics order, activation energy ( E ) and frequency factor ( s ). The proposed dosimeter exhibits simple glow curves, good linearity from 0.01 up to 4 Gy, easy annealing, excellent reproducibility and minimal fading. These attractive features will pave the way to its use in radiation dosimetry.
