摘要：

Thin films of Pb1-xCaxTiO3 [x = 0.20, 0.24 and 0.28] have been prepared on ITO coated Coming glass substrates by sol gel technique. The perovskite phase of PCT films is formed at 650 T with a polycrystalline tetragonal structure. The tetragonal factor (c/a) decreases with increasing Ca concentration. Dielectric, pyroelectric and ferroelectric studies have been carried out on these films. The effects of introduction of Ca ion in PbTiO3 have also been discussed. (C) 2003 Elsevier Ltd.
