Low temperature coating of anatase thin films on silica glass fibers by liquid phase deposition

Abstract

Uniform crystalline TiO₂ thin films were coated on silica glass fibers by liquid phase deposition from aqueous solution of ammonium hexafluorotitanate at low temperature. TiO₂ thin films and nano-powders were prepared by adding H₃BO₃ into (NH₄)₂TiF₆ solution supersaturated with anatase nano-crystalline TiO₂ at 40 °C. The effects of the deposition conditions on the surface morphology, section morphology, thickness of the deposited TiO₂ thin films were investigated. The results indicate that the growth rate and particle size of the thin films were controlled by both the deposition conditions and the amount of anatase nano-crystalline TiO₂.
