摘要
The formation of ferroelectric Pb(Zr, Ti)O-3 thin films was carried out by spin-coating and pyrolysis of the metal naphthenates. The solution for spin-coating was prepared by mixing Pb, Zr and Ti naphthenates at the Pb:Zr:Ti molar ratio of 1.05:0.52:0.48. Homogenous precursor films spin-coated on Pt plates were heat-treated in air at 500 degrees C for 5 min for crystallization into the single-phase ferroelectric perovskite Pb(Zr, Ti)O-3. The resultant film shows good ferroelectric properties: the coercive field E(c) and the remanent polarization P-r were estimated to be 39 kV/cm and 24 mu C/cm(2), respectively.
