CuO and Co₃O₄ Nanoparticles: Synthesis, Characterizations, and Raman Spectroscopy

Figure 3

(a) AFM image of as prepared CuO nanoparticles (A) 3D, (B) 2D, and (C) line profile of CuO. From (A) and (B), it is confirmed that CuO particles are uniformly distributed on GaAs substrate. In addition, line profile (C) reveals that the size of CuO is around 10 nm. (b) AFM image of as prepared Co₃O₄ nanoparticles (A) 3D, (B) 2D and (C) line profile of Co₃O₄ NCs. From (A) and (B), it is confirmed that Co₃O₄ particles are uniformly distributed on GaAs substrate. In addition, line profile (C) reveals that the size of Co₃O₄ is around 9 nm.
