The （Bi0.9Ho0.1）3.999Ti2.997V0.003012.（BHTV） films have been prepared on Pt/Ti/SiO2.Si substrates by solgel method. The microstructure and ferroelectric properties of the BHTV films were investigated. The BHTV films show a single phase of Bi-layered Aurivillius structure and dense microstructure. The Ho3＋/V5＋ cosubstitution can effectively improve the ferroelectric properties. The BHTV film exhibits good ferroelectric properties with 2.r of 47.6℃/cm2. 2.c of 2.5 kV/cm （at applied field of 42. kV/cm）, dielectric constant of 305, dielectric loss of 0.031 （at 1 MHz）, good insulting behavior, as well as the fatigue-free behavior.

Sol-gel derived bismuth cerium titanate (BCT) thin films with different Bi contents in precursor solu- tions were deposited on the Pt/Ti/SiO2.Si substrates. The effect of Bi content in the precursor solutions on the microstructure and ferroelectric properties of the films was investigated. It is found that with Bi content increasing from 90% to 110% of the nominal value in the precursor solutions, the dissipation factor and leakage current density of the BCT films obtained decrease, while the grain sizes, dielectric constant and remanent polarizations (2.r) increase, and concurrently, a Bi-deficient phase of Bi2.i2.7 gradually disappears. The film prepared from solution with 110% of the nominal Bi content exhibits pure Bi-layered Aurivillius polycrystalline phase, and the 2.r value and coercive field value are 67.1 μC/cm2.and 2.9.7 kV/cm, respectively. Their dielectric constant and the dissipation factor are about 172.and 0.033 at 1 kHz, respectively. Moreover, this film shows no polarization fatigue after 4.46×109 switching cycles.
