| Research Abstract |
To investigate fundamental mechanism on the interactions between molecules and plasomnic nanoparticles which make confined electromagnetic field upon light illumination, we fabricated hybrid thin films consisting of gold or silver nanoparticles and photofunctional organic material such as photochromic compounds and fluorescent dyes. We have examined and revealed the effects of localized surface plasmon resonance of metal nanopaparticels on molecular photochemical processes by conventional and single particle spectroscopies.
