    Abstract

    When sol-gel synthesized silica glass containing about 260 ppm of OH groups is irradiated with an ArF excimer laser, photoluminescence appears at 1.9 eV (650 nm). From measurements of luminescence lifetime, the absorption spectrum and electron-spin-resonance spectroscopy, the luminescence is thought to be due to a non-bridging oxygen hole centre, a kind of point defect in silica glass.
