Excitonic photoluminescence spectra at T = 10 K of ZnO nanorod layers deposited at different spray rates. The layers are deposited from aqueous solutions onto ITO/SGL substrates at 550°C with spray rate of 1.2, 2.2, and 6.2 ml/min, illustrated by spectrum A, B, and C, respectively. Spectrum A is shown with fitting results. The inset in the Figure 6 shows spectrum A in logarithmic scale.
