我们报告了在纳米颗粒分散的光聚合物中全息记录期间纳米颗粒质量传递的实验验证。通过直接观察记录的全息图的微观结构以及光干涉图案和记录的全息图之间的相移的光学测量，我们发现全息曝光导致纳米颗粒从亮区域重新分布到暗区域，导致纳米颗粒的周期性组装，从而形成高对比度的全息图。
We report on experimental verification of mass transfer of nanoparticles during holographic recording in nanoparticle-dispersed photopolymers. Through direct observations of the microscopic structure of recorded holograms as well as optical measurements of the phase shift between the light interference pattern and a recorded hologram we find 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.
