Abstract
The luminescence properties of several doped materials are explored in many fields of application, including ionizing radiation dosimetry. These luminescence properties are essentially provided by the doping element. In this article, we report thermally stimulated luminescence (TSL) measurements of the trapping and recombination centers involved in the luminescence process of sol–gel-derived glasses. Three-doped species will be concerned: one transition metal (Cu), one rare-earth element (Ce), and a combination of both in the sol–gel silica matrix. By comparing the performances of these samples according to the criteria required for dosimetry by both TSL and optically stimulated luminescence (OSL) (sensitivity, dose response, and thermal fading), the results show that the simply doped samples really are potential candidates for fibered-OSL dosimetry.
