Highly transparent ZrO₂nanoparticle-dispersed acrylate photopolymers for volume holographic recording

Abstract

We demonstrate and characterize volume holographic recording in ZrO(2) nanoparticle-dispersed acrylate photopolymer films that have very low scattering loss. More than thirty-fold reduction in the scattering coefficient, as compared with those of previously reported TiO(2) nanoparticle-dispersed photopolymers, is achieved. 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.%. Dependences of nanoparticle concentration and grating spacing on the refractive index modulation are also investigated.

Optical Properties of Photopolymer Layers Doped with Aluminophosphate Nanocrystals

“…It has been previously shown [12][13][14][15][16][17][18][19][20][21][22] that the holographic recording process in nanoparticle doped photopolymerisable materials can lead to the redistribution of the nanoparticles and thus to the creation of patterns of particle rich and particle depleted areas ( Figure 1B). The diffraction efficiency, η, of such a volume phase hologram is given by (2):…”

Neutron Optical Beam Splitter from Holographically Structured Nanoparticle-Polymer Composites

“…In order to relate the properties of the actual gratings to those previously investigated [16,21] we first characterized them by light-optical diffraction experiments. They reveal two major common features for the gratings employing different nanoparticle species: (i) diffraction occurs clearly in the two-wave coupling regime (Bragg regime, i.e., only two diffracted beams propagate simultaneously) and (ii) the gratings are obviously nonsinusoidal for both nanoparticle species which is indicated by the existence of higher diffraction orders.…”

Diffractive-Optical Elements via All-Optical Patterning of Photopolymers and Nanocomposites

“…grating has been confirmed by holographical, phase shift and microscopic methods by us and other groups [10][11][12][13][14][15][16][17][18]. Figure 3a shows typical kinetics of the grating formation in the organic-inorganic nanocomposites containing different concentration of the NP (C NP ), (in this case, TiO 2 NP).…”
