我们已经制作了平面结构的银纳米粒子在单色明胶乳液与连续的间距范围从0.15-0.40微米，使用一个单一的激光源的双光束干涉。我们的平面全息图显示了一个丰富多彩的“彩虹”图案和光子带隙覆盖可见光和红外范围。我们采用有效介质方法对平面银纳米颗粒-明胶复合体系进行了模拟，理论与实验符合良好。
We have fabricated planar structures of silver nanoparticles in monochromatic gelatin emulsion with a continuous spacing ranging from 0.15-0.40 micron using a two-beam interference of a single laser source. Our planar holograms display a colorful "rainbow" pattern and photonic bandgaps covering the visible and IR ranges. We model the planar silver nanoparticle-gelatin composite system using an effective medium approach and good agreement is obtained between theory and experiment.
