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 Dy2O3 and P2O5. Dosimetric features include thermoluminescence (TL) glow-curve, annealing procedure, TL sensitiv...

Description
Summary: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 Dy2O3 and P2O5. 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.
