Abstract

Photochromism is the ability of a material to alter its optical density reversibly under the influence of activating light [1]. It must be pointed out at once that two classes of photochromic glasses are known: glasses sensitized [2, 3] by ions of variable valence (Eu, Ce, W, Mn, etc.) and glasses the properties of which are due to the presence of silver halide (AgHal) crystals. Other photosensitive crystals, such as ZnS, TiO2, etc., apparently may also produce this effect.
