The effect of prefiring temperature on the crystal structure and optical property of the Bi4Ti3O12 films on MgO substrates by using a metal naphthenate precursor was investigated. As-deposited films were prefired at 300 °C, 400 °C and 500 °C for 10 min, followed by annealing at 750 °C for 30 min. According to the pole-figure analysis, texture of the annealed films was found to depend on prefiring temperature. Transmittance and the variation of band gap with prefiring temperature were studied.
