Abstract
The purpose of this chapter is to report on a comparison of the IL data obtained under light and heavy ion irradiations as a means to reveal the different physical processes operating in each case. In all cases, recombination of self-trapped excitons (STEs) at color centers, Non-Bridging Oxygen Hole Centers (NBOHCs) and Oxygen-Deficient Centers (in particular, ODCII), created by irradiation, are assumed to be the predominant light emission process for the red (1.9 eV) and blue (2.7 eV) emissions, respectively. However, the comparison of the IL kinetics under light and heavy ion irradiations shows remarkable differential features. In particular, it reveals a coupling between the irradiation-induced structural damage caused by swift-heavy ion (SHI) irradiation and light emission. This coupling is absent for light ions due to their much lower structural disorder on the SiO\(_{2}\) network.
