From: High degree of polarization of the near-band-edge photoluminescence in ZnO nanowires

Figure 4

Polarization ratio of the PL emission from one of the analyzed nanowires. As a function of the photon energy for temperatures T = 70 K (full black curve) and 150 K (full red curve). The normalized PL spectra recorded at T = 70 K (dashed black curve) and 100 K (dashed red curve) are reported as reference. The inset reports the polarization ratio of the whole spectrum as a function of temperature.
