Zusammenfassung:The influence of the morphology of gold nanoparticles on the surface plasmon resonance was investigated experimentally and theoretically. Highly monodisperse bumpy gold nanoparticles of increasing size were synthesized, and the surface plasmon resonance wavelength shifted to longer wavelengths more rapidly with increasing particle size for bumpy particles than for spherical gold nanoparticles. The detailed surface morphology of bumpy gold nanoparticles was characterized by AFM, TEM, and SEM, and the optical properties were investigated on a single particle level. The comparison of the plasmon resonant properties between bumpy and spherical gold nanoparticles was also examined with a theoretical model
