Abstract: Nanocrystalline powder and thin films of calcium and lanthanum modified lead titanate (PCLT) were prepared by the sol-gel process. The structural variation of the powder with increasing annealing temperature was monitored by differential thermal analysis, thermogravimetric analysis, infrared spectroscopy and x-ray diffraction. The lowest temperature for the formation of nanocrystals was found to be about 400 °C. The size of the crystallites was calculated from x-ray diffraction data using Scherrer's equation. PCLT thin films were fabricated by spin-coating a sol-gel solution onto Si(100) substrates. By controlling the concentration of the precursor and the annealing temperature, homogeneous and crack-free thin films have been successfully prepared.
