Journal ArticleDOI
Holographic recording in TiO2 nanoparticle-dispersed methacrylate photopolymer films
TL;DR: In this article, the authors demonstrate permanent holographic storage in the green with high diffraction efficiency and recording sensitivity in TiO2 nanoparticle-dispersed methacrylate photopolymer films.
Journal ArticleDOI
Highly transparent ZrO(2) nanoparticle-dispersed acrylate photopolymers for volume holographic recording.
TL;DR: It is shown that the refractive index modulation as high as 5.3x10(-3), together with substantive photopolymerization-shrinkage suppression, is obtained at the nanoparticle concentration of 15 vol.%.
Journal ArticleDOI
Silica-nanoparticle-dispersed methacrylate photopolymers with net diffraction efficiency near 100%.
Naoaki Suzuki,Yasuo Tomita +1 more
TL;DR: In this paper, volume holographic recording in silica-nanoparticle-dispersed methacrylate photopolymers with reduced scattering loss as low as 2% was demonstrated.
Journal ArticleDOI
Holographic manipulation of nanoparticle distribution morphology in nanoparticle-dispersed photopolymers
TL;DR: It is found that holographic exposure causes nanoparticles to be redistributed from bright to dark regions, leading to periodic assembly of nanoparticles and thereby to formation of high-contrast holograms.
Journal ArticleDOI
Holographic nanoparticle-polymer composites based on step-growth thiol-ene photopolymerization
TL;DR: In this article, the photopolymerization kinetics and volume holographic recording characteristics of silica nanoparticle-polymer composites using thiol-ene monomers capable of step-growth polymerization are reported.
