摘　　要：Lead-free piezoelectric thin films of 0.055BaZrO_(3)–0.935(K_(0.45)Na_(0.5)Li_(0.05))NbO_(3)–0.01(Bi_(0.5)Na_(0.5))TiO_(3)(BZ–KNLN–BNT)were fabricated on(100)-LaNiO_(3)/SiO_(2)/Si substrates.The Pechini(polymeric precursor)method was carried out to prepare the complicated multi-component precursor solution.This method was suited for controlling the complex components accurately.The films crystallized at 700℃ showed a(100)pc-oriented perovskite structure,whose grain size was about 200 nm and thickness was about 700 nm.The Curie temperature Tc of the films was 292℃ that was near to that of the bulk ceramics.The preparation method used in this work provided a possibility for the application of multi-component lead-free piezoelectric films.
