Paper Abstract

Photonic crystals made of metals such as silver and gold have been theoretically demonstrated to exist complete photonic band gaps (CPBG). We studied the preparation of metallic-dielectric spheres, which have the same effect as metals and can be used to fabricate a new type of photonic crystals. By using the Electroless Plating Method, SiO2 spheres 300nm in diameter were coated with an about 20nm silver layer. The derived samples precoated with copper showed more homogeneous and much thinner silver layers compared with the directly coated ones. Our experiments also indicated that the sensitization and activation processes were necessary for the copper coating processes, although had little effect on the silver particle sizes as well as the layers thickness. Nuclear-growth mechanism is responsible for the deposition of both silver and copper nanoparticles on the surface of the spheres.
