The calculation of the kinetic parameters of a thermoluminescence
material (kinetic order (b), activation energy (E) and frequency factor (s)) by
using the thermoluminescence (TL) method is extremely important in determining
the kinetic characterization of the materials. Sodium Chloride (NaCl) is an inorganic salt. It is a crystal well known
for its luminescent properties, with a simple cubic structure and its band gap
is rather large (~ 8.5 eV). In this work, it was reported the TL response of
the material in the range of 50– 400 oC and calculated kinetic
parameters of sea salt. Two glow peaks were observed at 100 oC and 235
oC in the TL glow curve of sea salt with a heating rate 2 oC/s
after X-ray irradiation. The Tm-Tstop method was used to
determine the overlapping peaks under the main peak at 100 oC. With
the computerized glow curve deconvolution (CGCD) method, the peak analysis was
performed. In addition, kinetic parameters were calculated using various heating
rates and peak shape. The b = 1.5, E = 0.88 eV and s = 1.7x1011 s-1
values were calculated using the peak shape method.
