Abstract
- Silver nanoparticles deposited on TiO2 nanoporous films exhibited unique photochromic property under the irradiation of visible light. Here we investigated the application of photochromic Ag/TiO2 nanocomposite film in holographic data storage. Stable holographic fringes were formed on the Ag/TiO2 film using two coherent green lasers as writing beams, and these fringes could be erased with ultraviolet irradiation. These observations are consistent with the photochromism of Ag/TiO2 nanocomposite film and can be well explained by the visible light-stimulated dissolution and ultraviolet light-stimulated regeneration of silver nanoparticles in TiO2 matrix.
