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

Figure 2

XRD diffractogram of ZnO nanostructure samples fabricated at 300, 400, and 500°C, respectively. This growth can be observed from the presence of the peaks at 31.76, 34.32, 36.22, 47.56, 56.58, 62.84, 66.44, 68.04, 69.12, 72.7, and 76.94 which correspond to (100), (002), (101), (102), (110), (103), (200), (112), (201), (004), and (202) orientations, respectively. As shown in the XRD data, the (101) direction is the preferred orientation for the three samples. Reference corresponds to JCPDS card number 36-1451.
