Annotation	We improve a recently proposed approach for the evaluation of the thermal ionization barrier of the lanthanide excited states in luminescent materials by taking into account the effect of traps and their decay time temperature dependence. We present two distinct methods, and we apply them to the case of Lu2Si2O7:Pr. To this purpose, wavelength resolved thermally stimulated luminescence and photoluminescence time decay measurements extending up to the ms time scale have been performed.
