PLZT x/65/35 (x = 4, 8, 10) thin films were prepared by the acetic-acid based chemical solution deposition processing from lead tetraacetate, lanthanum nitrate and zirconium and titanium propoxides. Introducing top layer of PLZT with large PbO excess can prevent surface pyrochlore phase formation. It is further show that although lead is depleted from PLZT because of the reaction with the substrate, perovskite phase is retained as a consequence of a large lead-oxide content throughout the film.
