We have fabricated systems dispersed with metal nanoparticles, and examined the effects of increased scattering cross section and local electric field due to the surface plasmon resonance to the light diffusion and multiple scattering. Especially, the metal nanoparticle with a high anisotropic structure was prepared to examine the shape effects to the light diffusion. Optical functionalities based on multiple scattering of light have been elucidated. Examples include metal-nanoparticle-based random laser and optical hole burning. Moreover, the metal microparticle was found to enhance the birefringence of the matrix.

制备了金属纳米粒子分散体系，考察了表面等离子体共振引起的散射截面增大和局域电场对光扩散和多次散射的影响。特别是制备了具有高各向异性结构的金属纳米粒子，考察了形状对光扩散的影响。已经阐明了基于光的多次散射的光学功能。例如基于金属纳米颗粒的随机激光和光学烧孔。此外，还发现金属微粒增强了基质的双折射。
