Figure 1. The morphology and structure evolution of the starting metal oxides nanoparticles upon the laser irradiation in liquid.

(a), (d) and (g) TEM iamges of the starting nanoparticles of Fe₂O₃, CoO and NiO, respectively. (b–c), (e–f) and (h–i) TEM images of the synthesized products of Fe₂O₃, CoO and NiO, respectively. The insets in (c), (f) and (i) are the corresponding SAED patterns of the Fe₂O₃, CoO and NiO samples, respectively.
