Light scattering and nanoparticles

Metal oxide nanoparticles are finding increasing application in the preparation of new nanocrystalline materials, with metal oxide composites being used to confer new electronic, magnetic and optical properties into material structures. Often these materials are formulated and processed as slurries or aqueous suspensions. One key parameter in controlling the properties of such colloidal nanoparticle systems is their particle size. Light scattering techniques are widely used for its determination.
