英文摘要:

BiFeO3 nanoparticles were synthesized by a NaNO3-assisted low-heating temperature solid state reaction method.The effects of the molar ratio of added NaNO3 and the calcination temperature on the characteristics of the products were discussed.The structure,morphology,magnetic,optical and electrical properties of BiFeO3 were characterized by XRD,SEM,VSM and UV-VIS.The experimental results showed that the introduction of leachable inert inorganic salt as a hard agglomeration inhibitor in the mixture precursor led to the formation of BiFeO3 nanoparticles with uniform size.With the addition of NaNO3 in the process,the particle morphology decreased from a diameter of 300-500 nm to 80-100 nm.The BiFeO3 attained at 600 ℃C showed a smaller band gap (2.12 eV) and weak ferromagnetism at room temperature with a remnant magnetization value (Mr) of approximately 3.1×10-5 emu/g and a coercive filed value (Hc) of nearly 20 Oe.
