Achemical solution deposition route based on the chelate approach isdeveloped for the synthesis of Ba0.85Ca0.15Zr0.1Ti0.9O3thinfilms. This lead-free composition is regarded as one of the mostpromising for the replacement of Pb(ZrxTi1-x)O3 inpractical applications. The synthesis method replacesthe highly toxic 2-methoxyethanol route, and offers the advantage ofa simple and rapid preparation process. Homogeneous and crack-freethin films with thicknesses of 290 and 490 nm were prepared. Filmsannealed between 700 and 900°C develop a single-phase perovskitestructure. The electrical properties exhibitaweak frequencydependence for the dielectricconstant, low dielectric loss,andferroelectric behavior.p { margin-bottom: 0.21cm; direction: ltr; color: #00000a; line-height: 115%; orphans: 2; widows: 2; background: transparent }p.western { font-family: "Times New Roman", serif; font-size: 10pt; so-language: en-US }p.cjk { font-family: "Times New Roman", serif; font-size: 10pt; so-language: es-ES }p.ctl { font-family: "Times New Roman", serif; font-size: 10pt; so-language: ar-SA }em { font-style: italic }a:link { color: #0000ff; so-language: en-US; text-decoration: underline }
