Abstract
Ionoluminescence of α - quartz exhibits two dominant emission bands peaking at 1.9 eV. (NBOHCs) and 2.7 eV (STEs. The evolution of the red emission yield does not show a correlation with the concentrations of neither the NBOHC nor with that of other color centers. The blue emission yield closely follows the amorphization kinetics independently measured by RBS/C spectrometry. A simple theoretical model has been proposed; it assumes that the
formation and recombination of STEs are the primary event
and both, the light emissions and the lattice structural damage are a consequence this phenomenon. The model leads
to several simple mathematical equations that can be used to
simulate the IL yields and provide a reasonable fit to experimental kinetic data.
