Chapter 7 - Analysis of complex stimulated luminescence (SL) curves using analytical solutions of the one trap one recombination (OTOR) center model

Abstract

Thermoluminescence (TL) and optically stimulated luminescence (OSL) are widely applied passive radiation dosimetry methods. In most cases all experimental TL and OSL curves are complex, consisting of many overlapping single components. The useful physical information included in each curve include (a) the intensity of a specific component, which is used as a radiation dosemeter and (b) the physical parameters associated with the energy levels responsible for the individual components of these complex experimental curves. Both information is extracted by the computerized curve deconvolution (CCD), which analyses the complex curves into individual components. The cornerstone of the CCD technique is the model expression describing one single component. The main goal of this chapter is to provide a review on recently developed physical and not empirical equations termed master equations. The term “master equation'' is used here in the sense that a unique core equation can describe all stimulated luminescence effects at any stimulation rate.
