| Research Abstract |
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.
