Figure 2From: High degree of polarization of the near-band-edge photoluminescence in ZnO nanowires PL and μPL spectra. (a) PL spectrum of the NW ensemble collected at 4.2 K. (b) μPL spectra of two single nanowires (blue and red) collected at 4.2 K with a spectral resolution of 800 μeV.Back to article page
