Abstract

Perovskite Pb(Fe_1/2Nb_1/2)O₃ (PFN) coating films have been prepared on Si(100) and MgO(100) single crystal, and silica glass substrates by the sol-gel method using Nb(OC₂H₅)₅, Fe(NO₃)₃(DOT)9H₂O, and Pb(OC₃H₇ⁱ)₂ and Pb(CH₃COO)₂(DOT)3H₂O as starting materials. Five solutions with different preparation routes were used for dip-coating. Starting materials, mixing sequence of starting materials and substrate materials influenced the formation of PFN perovskite in the resultant coating films to a great extent. The use of Pb(CH₃COO)₂(DOT)3H₂O as lead sources and MgO(100) single crystal substrate lead to the direct formation of PFN coating films of single-phase perovskite. The results obtained are discussed in terms of macromolecules formed in coating solutions.
