Figure 7.

Normalized PL spectra. Spectra of the indium-doped ZnO nanostructures after annealing at different temperatures measured at temperatures of 20 and 300 K. The scale bars both show the blueshift energy change of the yellow-orange emission peak energy for the indium-doped ZnO nanostructures after annealing at different temperatures, respectively.
