我们证明了大量的收缩抑制纳米颗粒聚合物复合透射光栅通过使用的逐步增长聚合机制。结果表明，在纳米粒子浓度为35体积%时，聚合收缩率可降低至0.3%，由此在绿色中折射率调制和材料灵敏度分别最大化为8 × 10（-3）和1014 cm/J。我们的研究结果为全息存储材料的发展提供了一个显著的进步。(C)2010年美国光学学会
We demonstrate substantial shrinkage suppression of nanoparticle-polymer composite transmission gratings by use of the step-growth polymerization mechanism. It is shown that the polymerization shrinkage can be reduced as low as 0.3% at the nanoparticle concentration of 35 vol. % by which the refractive index modulation and the material sensitivity are maximized to be 8 x 10(-3) and 1014 cm/J, respectively, in the green. Our results offer a noticeable advance in the development of holographic data storage materials. (C) 2010 Optical Society of America
