From: Hierarchical ZnO Nanostructures with Blooming Flowers Driven by Screw Dislocations
SEM images of ZnO hierarchical structures as-synthesized.
(a), (c) and (e) are typical morphologies from the low temperature region to the high temperature region. (b), (d) and (f) are the corresponding enlarged images of (a), (c) and (e). The left panel in (b) is a type IA hierarchical structure with the spine of a V-shape belt and the right panel is type IB hierarchical structure with the spine of a rectangular belt. Numbers 1, 2 and 3 in (b), (d) and (f) mark single-layered, multilayered and multifid flowers, respectively. The scale bars are 100 μm for (a), (c) and (e), 20 μm for (b) and (d) and 10 μm for (f).
