    Abstract

    We have prepared nanocomplexes composed of silver or gold nanoparticles as a core and merocyanine or phthalocyanine as a shell portion by the co-reprecipitation method. From their absorption spectra, the core metal nanoparticles seemed to interact electronically with the shell layer of organic compounds in the nanocomplexes to give different electronic states from their original states. The morphology of their nanocomplexes was observed by electron microscopies.
