Rotor-like ZnO by epitaxial growth under hydrothermal conditions

摘要

Rotor-like ZnO was grown from a mixture of rod-like ZnO powder and a saturated Zn(OH)_4~(2-) solution under moderate hydrothermal conditions at 100 ℃, in which the precursor rod-like ZnO crystal plane acts as a matrix core, and the branched nanorods showed fast epitaxial growth on the six directions around the prism core.
