Non-empirical peak shape methods based on the physical model of the one trap one recombination center model.

Any experimental Thermoluminescent (TL) glow-peak contains the activation energy information of its corresponding energy level within the band gap in insulating materials. The theory of peak shape methods (PSM) correlates the macroscopic geometrical characteristics of a single TL peak with activation energy of the level responsible for the TL peak by assuming that the area under a TL peak can be approximated by the area of a triangle. In this way the geometrical characteristics becomes the measure of the activation energy.

Calculation of the half life for the thermoluminescent signal of Beryllium oxide.

Half-life is one of the fundamental parameters to characterize the thermoluminescent (TL) response in ionizing radiation dosimetry. In general, there are two types of important half-lives to model the phenomenon of thermoluminescence (TL). The first type of half-life is the time required for the concentration of trapped charge carriers in a single trap to decrease to half its initial value; this type of half-life is generally denoted as τ.

Effect of heating rate on MgBO:Tm,Dy glow curve and its kinetic parameters calculated with different methods.

This paper presents the results of a long experimental work carried out to study the influence of the heating rate (H.R.) on thermally stimulated light emission phenomenon, well known as thermoluminescence (TL) of MgBO activated by Tm and Dy ions (MgBO:Tm.

Kinetic parameters of thermally stimulated light emission phenomenon in CaF doped with Tm ions.

The characterization of new materials thermoluminescent used in radiation dosimetry, require the determination of kinetic parameters, which are associated with the number and shape of the peaks which presents its glow curve, among the most important are: the activation energy, E, or depth of the traps, the frequency factor, s, and the kinetics order, b. These parameters are necessary to predict the stability of thermoluminescent information after irradiation of the material. In this work, we present the results obtained for the determination of kinetic parameters of Tm-doped CaF, the methods used for the determination of kinetic parameters were; initial growth signal TL, General order Chen method, and Deconvolution of glow curve.

Luminescence detection and dose assessment of irradiated Yerba Mate (Ilex paraguariensis) tea leaves.

Imported commercial samples of Yerba Mate (Ilex paraguariensis) tea leaves were characterized by thermoluminescence (TL) and photoluminescence (PSL) physical methods. Samples of Yerba Mate were irradiated between 0.5-50Gy and 20Gy-5kGy gamma doses by using two different dose rates from (60)Co irradiators.
