Vibrational Order, Structural Properties, and Optical Gap of ZnO Nanostructures Sintered through Thermal Decomposition

Figure 1

TEM and SEM images of ZnO samples fabricated at (a–d) 300°C, (e–h) 400°C, and (i–l) 500°C. The insets on (a, b, e–g, and i) represent the size distribution of the structures. The arrow in (j) shows a hexagonal-like crystal present in the sample at 500°C.
