摘要：

Ferroelectric Pb(Fe0.5Nb0.5)O3(PFN)-PbTiO3(PT) thin films have been prepared on silica glass and silicon single crystal substrates by the sol-gel method using lead acetate, iron nitrate, niobium ethoxide and titanium tetraisopropoxide as precursors. It has been found that 38 mol% excess lead must be added to a starting solution to obtain single phase perovskite PFN coating films, while single phase perovskite 0.2PFN.0.8PT coating films can be prepared from the corresponding stoichiometric starting solution. The coating film shows a dielectric constant of about 500-1100 and dielectric loss of about 0.06-0.18 at 1000 Hz.
