Raman spectrum of ZnO nanorod layer deposited by chemical spray pyrolysis. The layer was deposited onto ITO/SGL substrate at growth temperature of 550°C, using aqueous solvent. SEM image of the corresponding ZnO nanorod sample is presented in Figure 3a. The Raman spectrum of the ITO/SGL substrate is shown with the dashed line.
