Thermoluminescent kinetics for negligible retrapping: Its application to the analysis of the glow curve of Y2O3: Eu+3

• A kinetics has been derived without resorting to the quasi-equilibrium approximation (QE).
• The expression for the glow curve does not contain derivatives.
• Analysis of the main glow peak of the Y2O3:Eu shows that the QE approximation does not always hold.

In this article a novel algorithm for analysing glow peaks resulting from traps having negligible retrapping is reported. The algorithm features two advantages: (1) an expression for the light intensity has been derived without resorting to the quasi-equilibrium approximation, and (2) no differential equation has to be integrated. The algorithm has been employed for analysing the main glow peak of Y2O3: Eu+3.
