| Research Abstract |
Synthesis of Au core/iron-oxide shell hybrid nanoparticles and fabrication of their self-assembled nanoparticle film have been developed to investigate optical modification of spectra through surface plasmon effect. We successfully synthesized Au core nanoparticle with 6nm in diameter covered by iron-oxide shell with 1.8~2.9nm in thickness. And we could observed the maximum absorption of the spectrum for the hybrid nanoparticle film at 580nm due to surface plasmon resonance, which was unchanged with that of the hybrid nanoparticle dispersion solution although showed a red-shift from that of Au nanoparticle dispersion solution. From this result, the surface plasmon resonance is very sensitive to dielectric constant of adjacent material to Au surface.
