Synthesis of Bismuth Ferrite Nanoparticles via a Wet Chemical Route at Low Temperature
Figure 5
Schematic for different chelating complex formed by tartaric acid (a) and citric acid (b), where purple stands for Bi, blue for Fe, red for oxygen, and gray for carbon atoms. (c) Possible formation processes of BiFeO3 NPs under wet chemical environment using tartaric acid and citric acid as chelating agents, respectively.
