Co-doped BaTiO3 thin films with the perovskite structure were prepared by pyrolysis of metalorganic compounds. According to optical-absorption and luminescence data, the introduction of Co had an insignificant effect on the Curie temperatureT C of the films (about 120δC), presumably because of the competitive effects of the Co dopant, reducingT C , and the large compressive strain due to the thermal expansion mismatch, raisingT C . An absorption band tentatively attributed to a small-radius polaron was observed in the near-infrared spectral region.
