Nanocrystalline lead titanate (PbTiO3 or PT) powder has been prepared by the sol-gel process followed by annealing at 700 degrees C. Using the spin-coating technique, 0-3 nanocomposite thin films of PT powder dispersed in a vinylidene fluoride-trifluoroethylene P(VDF-TrFE) copolymer matrix have been fabricated on glass substrates. The permittivity, pyroelectric coefficient, specific heat and pyroelectric figures-of-merit have been measured as functions of the volume fraction (phi) of ceramic for phi up to 0.12. All three figures-of-merit (current, voltage and detectivity) were found to increase with increasing phi.
