摘要：
Ion beam induced luminescence spectra have been in -situ recorded during He+ (2.5 MeV), O4+ (13.5 MeV) and Si4+ (24.4 MeV) irradiations for three vitreous silica grades with different OH content (KU1, KS -4V and Infrasil 301). Remarkable changes in the ionoluminescence spectra of the three silica grades were observed for low ion fluences. He+ irradiated samples exhibited higher luminescence than equivalent ones irradiated with heavier O4+ and Si4+ ions. KU1 samples with the highest OH content showed the lowest blue luminescence. Blue luminescence maximum during ion irradiations with O4+ and Si4+ ions is correlated with,structural changes. (C) 2016 Elsevier B.V. All rights reserved.
