Monoclinic CeTi2O6 thin film and sol-gel process for the preparation thereof

摘要

A monoclinic CeTi₂O₆ thin film and a sol-gel process for the deposition of CeTi₂O₆ thin films, which has applications as passive counter electrodes in electrochromic devices, sensors and photocatalytic agent is presented. This film can be obtained by spin coating a solution, which comprises both titanium and cerium precursors on to electrically conducting or insulating glass substrates and annealing at a temperature of 600° C. for 5 min. in air. The Ce:Ti mole ratio in the deposition sol for the preparation of the film is identified in the range of 0.4:1 and 0.6:1.
