Abstract

Abstract: A method for preparation of particle crystal film constructed from monodisperse silica
colloidal particles in diameter of about 300 nm is reported. The films were prepared from
an ethanol suspension by vertical deposition that relies on capillary forces to assemble
colloidal crystal particles on a vertical substrate. The 3D ordered films were
characterized by transmission spectra and scanning electric microscope (SEM). The effect of
evaporation temperature, particle concentration and sintered temperature on the quality of
colloidal particle crystal film was investigated.

Key words: colloidal Silica, self-Assemble, vertical deposition, colloidal crystal
