Abstract

The nature of the 2.7-eV photoluminescence in as-manufactured oxygen-deficient high-purity silica glasses is studied. Luminescence lifetime measurements and ab initio molecular-orbital calculations are consistent with the luminescence being a triplet-to-ground transition of a neutral oxygen-vacancy defect (?Si-Si?).
