Spectral changes induced by UV irradiation were studied in a variety of glasses. These include photosensitive glasses in which colloidal silver is formed, glasses in which the formation of V+ ions produces violet color, and glasses in which irradiation within a charge transfer band leads to the formation of Fe+2 ions and holes in the valence band. In all of these glasses, hole trapping by non-bridging oxygen atoms is required for the occurence of spectral changes.
