Figure 1: Schematic representation of thermally and optically stimulated luminescence phenomena. Luminescence techniques (TL and OSL) monitor the charges as they undergo radiative recombination with charge of opposite sign. Photoluminescence (PL) and Radiophotoluminescence (RPL) are also indicated in the figure.
