Shape effects in plasmon resonance of individual colloidal silver nanoparticles

Journal Article (Journal Article)

The effect of shape of individual silver colloidal nanoparticle on surface plasmon resonance was investigated by an optical detection technique combined with high resolution transmission electron microscopy (TEM). The geometrical shape of nanoparticle had a major role in determining plasmon resonance, while the spectrum redshifted with increasing particle size. Heat treatment was found to be capable of modifying particle shape, resulting in a change in its plasmon resonant properties.
