Image of FIG. 6.
FIG. 6.

Temperature-dependent excitonic peak energies of the AlZnO and AlInZnO nanorods. The formulas given in the figure are the result of simulations.

Image of FIG. 7.
FIG. 7.

Reciprocal temperature-dependent intensities of the of (a) AlZnO and (b) AlInZnO nanorods. The formulas and the red solid line in the figure are the result of simulation. The dotted line in Fig. 7(a) represents the curves simulated by activation energies of 6.6 or 18.2 meV. The inset in Fig. 6(b) shows the reciprocal temperature-dependent intensities of of InZnO nanorods and the corresponding fitting result.

Image of FIG. 8.
FIG. 8.

Temperature-dependent PLE spectra of (a) AlZnO and (b) AlInZnO nanorod arrays at 10 K. The dotted lines indicate the evolutions of the 3.335, 3.362, 3.379, and 3.388 eV positions.
