Outline of Final Research Achievements

The purpose of this study is to form the exciton polariton consists of LSPR and dye molecules with metal nanoparticles and porphyrin molecules. The metal nanoparticles dispersions were prepared chemically. The surface of the colloidal metal nanoparticles which were coated with cationic surfactant was modified by layered silicate to combine with cationic porphyrin electrostatically. The obtained hybrid exhibited high dispersibility even in concentrated electrolyte. Furthermore, the surface of the negatively charged hybrids was demonstrated to be modifilable with cationic mole-cules. The extinction spectra of the obtained hybrid complex (metal nanoparticle/layered sili-cate/dye) shows split which indicates the formation of exciton polariton.
