Paper Abstract

Hydrophilic SiO2-nanoperticals dispersed polyvinyl alcohol /acrylamide (PVA/AA) binder-based volume holographic recording photoloymers are fabricated. In this photopolymer, monomer-nanoparticle counter diffusion plays a fundamental and key role in hologram formation. The experimental results indicate that nearly 20% increase of diffraction efficiency together with refractive index modulation photopolymer films containing SiO2-nanoperticals contrast with traditional samples. The optimum concentration of SiO2-nanoperticals and the origin of diffraction efficiency enhancement are investigated. It is shown that the nanoparticles are uniformly dispersed in the sol-gel photopolymer and significantly influence on the grating formation. Additionally, the incorporation of inorganic nanoparticles into photopolymer leads to the substantive suppression of the volume shrinkage during holographic exposure.
