Resumen

Most of the existing methods for obtaining the frequency factors make use of the trap depth (activation energy) making assumptions about the order of the kinetics. This leads to inconsistencies in the reported values of trapping parameters as the values of the activation energy obtained by different methods differ appreciably among them. Then, it is necessary to employ a method independent of the trap depth as it is the case of the method that makes use of the isothermal decay of the thermoluminescence (TL). In this paper, the isothermal decay of TL was used to determine the trapping parameters of K₂YF₅:Tb. The results obtained by applying this method are in good agreement with those obtained using the glow curve shape method except in the value of the frequency factor.
