Abstract Ba_1-xCe_xTiO₃(0≤x≤0.08) nanotube thin films were prepared via hydrothermal method, anodized TiO₂ nanotube thin films as template. The structure, morphology and electrical properties of Ba_1-xCe_xTiO₃ nanotube thin films were investigated. The crystal structure was characterized by X-ray diffraction, the surface and fracture morphology was observed by scanning electron microscopy and transmission electron microscopy, and the dielectric properties were tested by broadband dielectric spectrometer. The result revealed that the Ba_1-xCe_xTiO₃ nanotube thin films diameter was between 80—95 nm with cubic phase which were prepared by hydrothermal method under mild conditions. The polycrystalline Ba_1-xCe_xTiO₃ nanotube thin film was formed after annealing, and the outer diameter of the tube was between 90—100 nm and the thickness of the tube wall was 25—30 nm, the dielectric constant of thin film in 1 kHz was 472, the dielectric loss was 0.41.
