Deconvolución y análisis cinético de la curva termoluminiscente del sistema Borato de Litio (Li2B4O7:Cu)

Lithium borates (Li 2 B 4 O 7 :Cu) are highly promising matrices in the field of biomedical sciences for the development of dosimeters. In this work the thermoluminescent glow curve (TL) of these systems was studied by using a deconvolution analysis with logistic asymmetric functions (DLAF); in order to determine the kinetic parameters and to explain the TL behavior of the material. DLAF analysis revealed nine individual TL curves as responsible for the whole experimental TL curve. According to the obtained kinetic orders, recombination processes were the predominant phenomena during the TL emission. FOM value (goodness of fit) of 2.1% confirms the validity of the DLAF as kinetic analysis method and, by doing so, it is very useful for the modeling and simulation of TL activity and sensitivity allowing the design of “tailor-made” dosimeters for specific applications.
