Abstract

Abstract: ESR method was used to study the properties of paramagnetic centers generated by γ-irradiating silica gel containing respectively phosphorus and boron as impurity ions. Oxygen holes O^- were found to be stablized close to impurity ions. In addition, O₂^- radical and F colour center signals were observed and investigated. A dynamic equilibrium process would exist during F centers formation.

Key words: Doping SiO₂, γ-irradiation, ESR, O₂^- radical, O^- hole center
