Simulation of Radioluminescence Processes in Cerium-doped silica glasses

Abstract

International audienceRare-earth-doped silica glasses are promising materials for ionizing radiation dosimetry. Indeed, under such radiations, these materials present an interesting real-time radioluminescence (RL) signal. In this paper, we study RL of Ce-doped silica glasses using a kinetic model involving one or several trapping states and one recombination center. Using appropriate sets of trapping parameters for the kinetic model, the RL signal along with the occupancies of the relevant traps and center are simulated numerically. Several experimentally observed characteristics of the RL signals are explained using the model
