From: Photoluminescence of spray pyrolysis deposited ZnO nanorods
Normalized photoluminescence spectra of ZnO nanorod layers deposited using different solvents. The layers are deposited onto ITO/SGL substrate at 480°C from aqueous or alcoholic solution, illustrated by spectrum A and B, respectively. Spray rate is kept similar (2.2 ml/min). Spectrum A is shown with fitting results. SEM image of the sample corresponding to spectrum B is presented in Figure 3c.
