Figure 3From: Photoluminescence of spray pyrolysis deposited ZnO nanorods SEM images of ZnO nanorod layers deposited by chemical spray pyrolysis. The layers (a, b, c) were deposited onto ITO/SGL substrate at growth temperature of 550°C (a) or 480°C (b, c) using aqueous (a, b) or alcoholic solutions (c) at similar spray rate (2.2 ml/min).Back to article page
