Ordered nanocrystal/silica particles self-assembled from nanocrystal micelles and silicate.
Ordered gold nanocrystal/silica particles were synthesized through self-assembly of nanocrystal micelles and silicate. Depending on the use of surfactants, and the kinetic conditions of silica hydrolysis and condensation, well-shaped and irregularly-shaped silica particles were formed, inside which the nanocrystals self-organized in a face-centered cubic mesostructure.
