- W1998248932 abstract "Direct experimental evidence for the presence and x-ray dose dependence of radiolytically displaced oxygen in high-purity, oxygen-deficient a-${mathrm{SiO}}_{2}$ is presented. Anneal-interrupted x-irradiation and electron spin resonance measurements were used to investigate the x-ray dose dependence of the radiation response of two types of low-OH a-${mathrm{SiO}}_{2}$, i.e., oxygen-excess and oxygen-deficient materials. The production and thermal annealing of paramagnetic defects in these two materials were compared to explore the role played by dissolved and radiolytically displaced oxygen in these processes. The multiple, reversible interconversions of ${mathit{E}}^{ensuremath{'}}$ centers and peroxy radicals proved to be very sensitive to the presence of free oxygen in the a-${mathrm{SiO}}_{2}$ network. Such interconversions are very probable in the oxygen-excess material due to the presence of dissolved oxygen. It follows that such interconversions are not expected in the oxygen-deficient material, at least at low dose, in agreement with experimental data. However, our results show that such interconversions take place above a certain threshold dose in oxygen-deficient material. In fact, we observed peroxy radicals in oxygen-deficient material. Their production is attributed to the presence of radiolytically displaced oxygen in this material.A simple physical model is presented to explain the results. The model involves the random creation of displaced oxygen atoms which undergo elastically driven recombination into oxygen molecules. It is these molecules which participate in the interconversions in the oxygen-deficient material. A threshold is observed because the recombination does not occur unless the distance between the oxygen atoms is less than some characteristic length, i.e., a correlation radius of an elastically coherent nanoregion in the amorphous network. The experimental results and the model imply a universal radiation response at high dose when the density of radiolytically displaced oxygen exceeds that of any precursors. textcopyright{} 1996 The American Physical Society." @default.
