Analysis of the glow curve of KMgF3:Lu compounds without resorting to the quasi-equilibrium approximation

In this article we report an expression for the thermoluminescence light, which is derived from the set of differential equations by assuming negligible retrapping, but without resorting to the quasi-equilibrium approximation. The expression has been employed for analysing the glow curve of KMgF3:Lu...

description In this article we report an expression for the thermoluminescence light, which is derived from the set of differential equations by assuming negligible retrapping, but without resorting to the quasi-equilibrium approximation. The expression has been employed for analysing the glow curve of KMgF3:Lu fluoroperovskite compounds. •Glow curves of KMgF3:Lu have been analysed without resorting to the QE approx.•The glow curves have been analysed taking into account interactions among traps.•The algorithm used will not become stiff.•The kinetics parameters obtained do not depend on the dose.•The agreement between the two sets of parameters obtained shows that the QE approximation does not hold.
