Figure 4

Photoluminescence spectra at 10 K of the spray pyrolysis-deposited ZnO nanorod layers. The layers were deposited from aqueous solution onto SGL or ITO/SGL substrates, illustrated by spectrum A and B, respectively. The growth temperature (550°C) and spray rate (6.2 ml/min) were kept similar. The inset shows the photoluminescence spectrum at 300 K in region of 2.0-3.4 eV, characteristic of ZnO nanorods deposited onto ITO/SGL substrate at temperature of 550°C.
