The filling-factor tunable titanium dioxide replicas of colloidal crystals were fabricated by using the technique of liquid phase deposition (LPD). Ammonium hexafluorotitanate was used as a precursor which converted to titanium dioxide by hydrolysis with boric acid. The filling factor of the replica could be increased in a controllable fashion by applying the LPD process to the replica again. The results showed that the liquid phase deposition process was a convenient method for continuously adjusting the position of the stop band in titanium dioxide colloidal crystal replicas.
