Low Temperature Synthesis of BiFO3 Film by Hydrothermal Method

Abstract:

Article Preview

Polycrystalline BiFeO3 multiferroic films were fabricated on Ti substrates by hydrothermal method from an aqueous Bi (NO3)3•5H2O, FeCl3•6H2O and NaOH solution. The films grow in alkaline solution at low temperatures of 120°C-240°C for 18 hours. XRD analysis showed that well-developed crystallines with single perovskite crystal phase were obtained. It was also found that the increase of reaction temperature and concentration of NaOH were favorable for crystal growth and crystallographic regularization. The microstructure, thickness and cross-section of the films were characterized by FE SEM and EDS. Results indicated that dense and homogeneous BiFeO3 thin films could be obtained in an appropriate hydrothermal condition.
