We developed a route to fabricate environmental friendly lead-free ferroelectric Ba0.85Ca0.15 (Ti0.9Zr0.1)O3 (BCZT) thin films by chemical solution deposition. The precursor solution was prepared by mixing starting solutions of calcium and barium acetate, and alcoholic solutions of titanium (IV) butoxide and zirconium (IV) propoxide using acetoin (3-hydroxy-2-butanone) as chelating agent. The films were obtained by the spin coating method on platinum substrates (Pt/TiO2/SiO2/Si). Different strategies for the optimization of the route were tested by investigating the evolution of the crystal structure of films treated at different temperatures between 650 and 900 ºC. Atomic Force Microscopy was used to examine the morphology. Finally the films were electrically tested by dielectric and ferroelectric measurements.
