新近开发出的具有长周期的纳米多孔金材料的光学特性可能会产生一些光子学应用。在紧密排布的聚苯乙烯乳胶微球体 (直径从 30 0 nm到 1μm)之间挤压胶状金纳米颗粒 (直径 15～ 2 5nm) ,然后除去这些微球体 ,通过这种方法就可以制备多孔金纳米结构材料。1997年 ,一组来自特拉华
The newly developed optical properties of long-period nanoporous gold materials may generate some photonics applications. Colloidal gold nanoparticles (15 to 25 nm in diameter) are extruded between tightly packed polystyrene latex microspheres (30 to 1 μm in diameter) and then these microspheres are removed and prepared in this way Porous gold nanostructured materials.
