Monodisperse colloidal SiO2 submicrospheres were prepared by hydrolysis and condensation of tetraethoxysilane. We measured various relative settle velocities of different aggregated submicrospheres and then developed a submicrospheres selection technique separating single spheres from aggregated spheres. Monodispersity Of SiO2 submicrospheres was improved by this submicrospheres selection technique. Higher-quality SiO2 opals were fabricated from selected submicrospheres., (C) 2002 Elsevier Science B.V. All rights reserved. |
