- Abstract
Data are presented to show how fluorination influences the optical quality and radiation resistance of quartz glasses fabricated by the sol gel method. It is found that under the action of gamma radiation, mainly E' centers form in the glasses. The incorporation of fluorine in the xerogel lattice promotes the removal of hydroxyl groups and enhances the radiation optical resistance of the synthesized samples in the red. It is observed that the radiation resistance of the glass is enhanced in the ultraviolet by using irradiation-annealing cycles and this is attributed to a decrease in the concentration of radiation-induced E' centers.
