Abstract—Zinc oxide low-dimensional hollow structures in the form of hexagonal plates with holes at the cen-
ter of the {0001} facets are synthesized in the course of the low-temperature interaction of ZnO precursors with
aqueous solutions of potassium fluoride under hydrothermal conditions. Crystals have the shape of single-
walled or multiwalled “nuts.” The high optical quality of the structures is confirmed by cathodoluminescence
data at room temperature. The mechanism of the formation of ZnO “nanonuts” and products of the interaction
of the ZnO precursors with KF is proposed.
