| Description | Understanding and characterization of colloidal nanoparticles is very important for their uses in the research and technology. Colloidal silver solutions have many interesting properties such as surface plasmon resonance. Plasmons are optical effects observed for silver, gold, and copper and the other nanoparticles. The value of the wavelength of this effect depends on the particle size and shape as well as on the properties of solvent or absorbent presented. As sample there were used nanoparticles of silver, which were dispersed in aqueous solution. The fluorescence, size and zeta-potential of two samples each with different date of preparation were measured. The colloidal solutions were investigated by means of fluorescence spectroscopy, dynamic light scattering, electron microscopy, and electrophoretic light scattering for zetapotential evaluation. |
