Outline of Final Research Achievements

The development of the metal surface texturing and the surface functionalization based on the combination of the top-down method using laser processing with the self-organization in a metal nanoparticle/organic molecule hybrid film was aimed in this study. A hybrid film with a self-organization structure was prepared by spin-coating on a substrate from the mixture solution of metal nanoparticle and POSS (polyhedral oligomeric silsesquioxane）molecule. The metal surface with a micro-texture was formed by laser beam irradiation and the scanning. A film surface with a macropore structure consisting of silver nanoparticles showed the hydrophobicity and the application possibility of a sensor substrate for surface enhanced Raman scattering: (SERS).
