Preparation and Preliminary Nonlinear Optical Properties of BiFeO<sub>3</sub> Nanocrystal Suspensions from a Simple, Chelating Agent-Free Precipitation Route

<div>(a) <i>ζ</i>-Potential variations as a function of pH for amorphous precursors precipitated at KOH = 4 M (blue) and after crystallization (red). Inset: pictures taken just after dispersion (first row) and after a sedimentation period of 5 days (second row) for the crystallized powders dispersed at pH values fixed at 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, and 10.0 (from left to right). (b) TEM image of the amorphous powders precipitated at KOH = 4 M.</div>
