Query: Revealing trap depth distributions in persistent phosphors with a
  thermal barrier for charging   The performance of persistent phosphors under given charging and working
condition is determined by the properties of the traps that are responsible for
these unique properties. Traps are characterized by the depth of their
associated thermal barrier and a continuous distribution of trap depths is
often found in real materials. Accurately determining trap depth distributions
is hence of importance for the understanding and development of persistent
phosphors. However, extracting the trap depth distribution is often hindered by
the presence of a thermal barrier for charging, which causes a
temperature-dependent filling of traps. For this case, we propose a method for
extracting the trap depth distribution from a set thermoluminescence glow
curves obtained for variable charging temperature. The glow curves are
transformed into electron population functions via the Tikhonov regularization
in the framework of first-order kinetics. Subsequently, the evolution of the
occupation of the traps as a function of trap depth, quantified by the
so-called filling function, is obtained. Finally, the underlying trap depth
distribution can be reconstructed by two proposed methods. The proposed method
provides good precision and resolution for the trap depth distribution, which
is a step forward in acquiring a deeper understanding of the (de)trapping
behavior of persistent and storage phosphors.
