Influence of pH, Precursor Concentration, Growth Time, and Temperature on the Morphology of ZnO Nanostructures Grown by the Hydrothermal Method

<table>(a) shows the AFM image of the seed layer and the corresponding height profile. (b) SEM image of ZnO NSs on Si substrate grown with different aqueous solutions of pH value 1.8; (c) at pH value of 4.6; (d) at pH value of 6.6; (e) at pH value of 9.1; (f) at pH value of 10.8; (g) at pH value of 11.2.The insets show enlarged SEM images of ZnO NSs (scale bar = 100 nm).</table>
