摘要：
We synthesize zinc sulfide (ZnS) nanoparticles with a diameter of similar to 5 nm and formulate novel photopolymer/ZnS, nanocomposites for holographic. recording. By taking advantage of the photoinitibitor;, composed of 3,3'-carbonylbis-(7-diethylaminocoumarin) (KCD) and N-phenylglycine (NPG), With a capability of spatiotemporally tailoring the grating formation process, we successfully achieve high, performance holographic photopolymer/ZnS nanocomposites with as. high as 93.6% of diffraction efficiency (eta), 26.6 x 10(-3) of refractive index modulation (n(1)), 8.4 per 200 mu m of dynamic range, and 9.8 cm/mJ of photosensitivity. In addition, Jot an aim of toughly. describing the grating formation process, we establish a navel exponential correlation between the ZnS nanoparticles segregation degree (SD) and the ratio of photopolymerization gelation time (t(gel)) to holographic mixture viscosity (v). Finally, we reconstruct and display 3D images that are dearly identifiable to the naked eye through a master technique, opening a versatile class of potential applications in high capacity data storage, stereoadvertisements, and anticounterfeiting.
