PCT thin films were prepared on (100)Si and fused quartz substrates by sol-gel process. The crystal structure was investigated using XRD and the results show that PCT thin films have a perovskite phase structure. SEM and AFM were respectively used to observe the surface morphology of the thin films. The films were homogeneous and crack-free. In the PCT30 thin films on (100)Si substrate, the average grain size was 55 nm when annealed at 700℃.The optical transmission spectra of PCT thin films were measured in the wavelength range 190-1000 nm. The films have good optical transparent properties. The band gap energy of the films decreases with the rise of annealing temperature.
