Abstract
- Thermally stimulated luminescence (TSL) properties of cerium and terbium doped SiO2 sol-gel glasses were studied after X-ray irradiation in the temperature range 10-700 K. The role of Ce3+ and Tb3+ as recombination centers was shown. The existence of a distribution of trap levels was observed; the activation energies of such a distribution were calculated to extend from about 8 x 10(-3) eV up to 1.8 eV for both cerium and terbium doped sol-gel glasses. The effect of a post-densification thermal treatment on TSL properties was also analyzed. (c) 2005 Elsevier B.V. All rights reserved.
