, PT, thin films prepared by spin-coating of nano-powder incorporated carboxylates were systematically examined. Comparing to the direct synthesis of PT films by metal-organic decomposition process, the incorporation of nano-sized PT powders into the carboxylates markedly modifies the crystallization kinetics of the PT films. Pure perovskite phase can be obtained by post-annealing these films at 600°C for 1 h and the remanent polarization for the films can be optimized only by post-annealing at high enough temperature (650°C). However, the nano-powder incorporated PT films possess pronouncedly lower remanent polarization (P
r
) and smaller coercive field (E
c
) than the non-powdered PT films. Such a phenomenon is ascribed to the formation of multi-grain structure in each column of the films. |
