Abstract

Abstract Vacuum-ultraviolet (VUV) absorption of O 2 and H 2O molecules incorporated in interstitial voids in SiO 2 glass by thermal annealings was examined. Interactions of the interstitial molecules with the surrounding SiO 2 glass network lead to a redshift of the VUV absorption band of interstitial O 2, while a blueshift of that of interstitial H 2O, both accompanied by an increase in the intensity of the absorption bands. The Coulomb repulsion, London dispersion, and hydrogen bonding are the main interactions responsible for the modification of the VUV absorption bands.
