We report the observation of photoluminescence (PL) originating from defects created by the visible and near-infrared irradiation of vitreous silica. Three PL bands at 283, 468, and 558 nm exhibited excitation spectra peaking at 250 nm, which corresponds to the oxygen vacancy defect VOabsorption. The observed PL bands can be attributed to the following transitions: the singlet-singlet transition of oxygen vacancy for 283 nm, and the radiative recombination of separated carriers on the vacancy-interstitial pairs (VO;Oi) and (VO;(O2)i) for 468 and 558 nm, respectively.
