Dynamic transition between Zn-HDS and ZnO; Growth and dissolving mechanism of dumbbell-like ZnO bipod crystal

Abstract

The dumbbell (DB) ZnO bipod crystal is directly grown from acetate anion intercalated Zn based hydroxyl double salts (Zn-HDS). Our results suggest that the (0001)-to-(0001) plane orientation of the DB ZnO crystal comes from the acetate anions intercalated into the Zn-HDS. The DB ZnO crystal is dynamically changed to tube, nanoplate, and the new Zn-HDS with interlayer spacing of 20.0Å by etching the (000-1) surface. © 2011 The Royal Society of Chemistry.
