The photosensitive effect is superficial under ultraviolet (UV) irradiation but occurs in the entire volume of the glass under visible irradiation. The effect can be obtained in any specific point inside the volume using an infrared femtosecond laser. In addition, the photosensitive phenomenon can be erased by specific heat treatment. This glass can be useful to substitute actual data storage supports and is a promising material for 3-dimensional (3D) and holographic optical storage.3engArtigo10.1063/1.2364476WOS:000241722000001Acesso abertoWOS000241722000001.pdf2998503841917815644604746303465433495868807467350000-0003-3286-9440
