Thin films of Pb0.80Ca0.20TiO3 and Pb0.76Ca0.24TiO3 are prepared using the sol-gel technique on ITO coated corning 7059 glass. X-ray diffraction studies on these films show perovskite structure with tetragonal phase. Dielectric, pyroelectric and ferroelectric studies are carried out on these films. Results suggest that PCT76/24 with pyrocoefficient (43 nC cm−2 K−1) and voltage responsivity (2340 V cm−2 J−1) is a promising pyrosensor material.
