Sol-gel preparation of PZT thin films with BaTiO3 seeds

Abstract

The lead zirconate titanate (PZT) thin films, with Zr/Ti ratio of 52/48 have been synthesized by the sol-gel method. Perovskite barium titanate (BaTiO3) nanopowders have been introduced in the precursor sols as seeds, to induce the perovskite phase formation at low temperatures. Their effect on the phase formation process, during the crystallization of PZT thin film was studied. Pure perovskite PZT thin films were obtained at 550 degrees Celsius and 600 degrees Celsius, when 5 mole% and 1 mole% perovskite BT crystalline seeds were used, respectively.
