Abstract
In this chapter we summarize the experimental techniques and models for continuous wave and linearly modulated infrared stimulated signals (CW-IRSL and LM-IRSL). We provide a general description of luminescence signals within the excited state tunneling model (EST) and show how these IRSL signals can be evaluated by integrating over the distribution of distances between pairs of nearest donors and acceptors in the material. We present Python simulations for the analytical Kitis Pagonis equations (KP-CW and KP-LM) and demonstrate how they depend on the parameters of the EST model. We discuss the stretched exponential function which has been shown to describe a variety of relaxation phenomena in solids, and show how it can be used to describe CW-IRSL signals. In the next chapter we will apply the EST model and the KP equations to the deconvolution of IRSL signals.
