在含有直径为30 ~ 40 nm的球形银纳米颗粒的玻璃中，相对容易地制造出衍射光学元件，并将其嵌入到厚度约10 μm的表面层中。纳米复合材料被夹在网格金属电极和平板金属电极之间，网格金属电极具有2 μm的晶格常数，面对纳米颗粒包含层并作为阳极，平板金属电极作为阴极。在200 °C的高温下在纳米复合材料上施加0.4kV和0.6kV的中等直流电势30分钟，导致形成金属纳米颗粒的嵌入结构的周期性阵列。的结构化过程中的电流-时间动力学，光学分析的结构化的纳米复合材料和一个这样的制造元件的衍射图案。
A diffractive optical element is fabricated with relative ease in a glass containing spherical silver nanoparticles 30 to 40 nm in diameter and embedded in a surface layer of thickness ~10 μm. The nanocomposite was sandwiched between a mesh metallic electrode with a lattice constant 2 μm, facing the nanoparticle containing layer and acting as an anode, and a flat metal electrode as cathode. Applying moderate direct current electric potentials of 0.4 kV and 0.6 kV at an elevated temperature of 200 °C for 30 minutes across the nanocomposites led to the formation of a periodic array of embedded structures of metallic nanoparticles. The current-time dynamics of the structuring processes, optical analyses of the structured nanocomposites and diffraction pattern of one such fabricated element are presented.
