Monodisperse polystyrene (PS) particle multilayers with coherent structure were constructed by Langmuir-Blodgett (LB) method. The reflectance spectra of the particle multilayers with various incident angles indicated that the constructed particle multilayers showed a typical optical character of the conventional multilayers having different refractive indices. It was suggested that the particle multilayer could be treated as a multilayer constructed by polymer layer and air layer. The fact was strongly supported by a simulation of the corresponding model, which was designed for analyzing optical characterization of the particle multilayer. The refractive index of the particle multilayer with nickel ion was also discussed by simulation, suggesting that a theoretical designing of the particle multilayer with various refractive indices would be possible. It was also suggested that coordination of metal ion on the surface of the particle would be enhanced its contribution to increasing the refractive index.
