The kinetic parameters of the main thermoluminescence glow peak of Al2O3:C,Mg: A critical evaluation of different analytical methods

Carbon and magnesium co-doped aluminum oxide (Al2O3:C,Mg) is a highly sensitive luminescence dosimeter with promising use in wide spectrum of radiation-related applications, including neutron dosimetry as fluorescent nuclear track detector (FNTD). The goal this work to critically evaluate diverse methods approaches for the determination kinetic parameters using Al2O3:C, Mg case study. was beta irradiated doses from 0.1 0.6 Gy. Besides thermoluminescence (TL) peaks at 325, 350, 375 K, analysis activation energy, frequency factor order kinetics focused exclusively on main TL peak 450 K. Analysis by curve fittings used number freeware, namely, Glowfit, TLAnal, Thermoluminescence Glow Curve Deconvolution (TGCD) package, spreadsheet TLDecoxcel. results computational were compared obtained analyzing experimental data conventional initial-rise, whole glow peak, variable heating rate shape. performance satisfactory values found are consistent ones determined listed above.
