Preparation of 3D Colloidal Crystal Film and Gold-Infiltrated Silica Artificial Opals

Abstract
A free-standing 3D colloidal crystal film(opal)was fabricated at a water-air interface using purified monodispersed SiO2 colloids.The gold/silica opal was obtained through the infiltration of gold nanoparticles by electroplating.The transmission and reflection spectra of the gold/silica composite opal show a red shift with increasing electroplating time.SEM images show that gold nanoparticles can be directly deposited on the surface of silica spheres in the opaline structure.Gold/silica composite opal film could provide a simple way to tune opal properties through controlling the amount of gold in the silica opal.-
