Figure 3.

Room-temperature PL spectra, PL intensity, and FWHM value of the samples. Room-temperature PL spectra of the (a) ZnO nanorods with no seed layer, (b) ZnO NRAs/zinc acetate seed layer, (c) ZnO NRAs/MWCNT (2 wt.%)-composed seed layer, and (d) ZnO NRAs/MWCNT (5 wt.%)-composed seed layer on ITO/glass. The inset shows the PL intensity and the FWHM value of the corresponding samples.
