Abstract

Formation processes of the peroxy radical (POR) were examined in high-purity SiO₂ glass exposed to F₂-laser light which creates mobile atomic oxygen (O°) by photolyzing the interstitial oxygen molecules (O₂). It was proved that under these conditions POR is formed by a reaction of the non-bridging oxygen hole center (NBOHC, an oxygen dangling bond) with O°, not by a reaction between the E' center (a silicon dangling bond) and O₂. Subsequent exposure to KrF laser light photolyzes POR and recoveres NBOHC by dissociating the O-O bond in POR. These findings corroborate the important role of O° in defect processes in SiO₂ glass.
