Evolution of microstructure and optical property with annealing temperature has been examined for Ba 0.9 Sr 0.1 TiO 3 films derived from one single precursor solution containing polyethylene glycol polymer. The films sintered below 750°C exhibit a uniform phase structure across the cross-sections and an ordinary optical thin film feature, while the Ba 0.9 Sr 0.1 TiO 3 films crystallized at 750°C or higher temperature render a lamellar texture consisting of dense and porous Ba 0.9 Sr 0.1 TiO 3 layers and a good performance as a one-dimensional photonic crystal. The discrepancy in cross-sectional morphology and reflectance property observed in these Ba 0.9 Sr 0.1 TiO 3 films has been preliminarily explained.
