Abstract

Organic-inorganic nanocomposite films were prepared by dispersing an aromatic methacrylic monomer and a photoinitiator in organic-inorganic hybrid sol-gel matrices. The film properties could be controlled by optimizing the content of an organically modified silica precursor (TSPEG) in the sol-gel matrices. The photopolymer film modified with the organic chain (TSPEG) showed high diffraction efficiency (>90%) under an optimized condition. In addition, we implement a digital holographic security system that combines the electrical biometrics technology with fully digital holographic storage using an organic-inorganic hybrid type photopolymer film.
