PZT thin films embedded with WO3 nanoparticles were prepared by a hybrid chemical solution process. WO3 at 0, 0.1, 0.2, 0.3, 0.4, 0.5 and 1 wt% nanopowders were suspended in an organometallic precursor solution of PZT, and then coated on platinized silicon substrate using spin-coating technique. The increase of WO3 resulted in a reduction of densification of the films. However, at 1 wt% WO3 concentration, the reaction between PZT and WO3 occurred during heat-treatment process at 600°C and seemed to improve the film's density. The WO3 nanoparticles were also found to affect both dielectric and ferroelectric properties of PZT films. Moreover, the addition of WO3 nanoparticles was found to improve a fatigue phenomenon in ferroelectric PZT thin films. Copyright© Taylor and Francis Group, LLC.
