论文摘要
我们证明了在光学和慢速波长下构建具有较大饱和折射率调制幅度的全息纳米颗粒聚合物复合传输光栅中的使用，从而有效地控制了光和慢速束。 Nanodiamond在光学波长和较大的连贯和小不相干的散射横截面上具有较高的折射率，在慢速中子波长下吸收较低。我们描述了纳米原子的合成，即光聚糖纳米座 - 聚合物复合膜的制备，纳米座 - 聚合物复合膜中传输光栅的构建以及光光学衍射实验。 Results of slow-neutron diffraction from such gratings are also presented.
We demonstrate the use of nanodiamond in constructing holographic nanoparticle-polymer composite transmission gratings with large saturated refractive index modulation amplitudes at both optical and slow-neutron wavelengths, resulting in efficient control of light and slow-neutron beams. Nanodiamond possesses a high refractive index at optical wavelengths and large coherent and small incoherent scattering cross sections with low absorption at slow-neutron wavelengths. We describe the synthesis of nanodiamond, the preparation of photopolymerizable nanodiamond-polymer composite films, the construction of transmission gratings in nanodiamond-polymer composite films and light optical diffraction experiments. Results of slow-neutron diffraction from such gratings are also presented.
