摘要：
Isotope labeling has been widely used to study reactions involving oxygen species in amorphous SiO2 (alpha-SiO2). This article briefly describes recent progress in O-18 labeling techniques to study reactions involving interstitial oxygen molecules (O-2), which is one of the most important excess oxygen species in alpha-SiO2. The primary focus will be on the combination of the O-18 labeling with photoluminescence spectroscopy, which enables sensitive and selective detection of interstitial O-2. Advantages of this method and results of evaluation of oxygen exchange between interstitial O-2 and the Si-O network of alpha-SiO2 will be presented. (c) 2012 Elsevier B.V. All rights reserved.
